Move your data to
the cloud, securely.
Cloud migration is moving your servers, databases and applications from their current environment to a professional data center without downtime. DataKobi handles the process end to end: from discovery to live synchronization, from final cutover to 30 days of hypercare. The migration is free, and your data never leaves Türkiye.
What is cloud data migration, and why now?
Cloud data migration is the transfer of the workloads in your server room or rented racks (virtual machines, databases, file servers, applications) to a professional data center services infrastructure, where they are run under a managed cloud model. The goal is not just to change location: it is to get away from hardware refresh cycles, outage risk and night-time on-call duty, and move to a predictable monthly cost.
There are three signs that the timing is critical. The first is hardware age: if your servers are 4-5 years old, the coming refresh investment equals years of a cloud subscription, and the risk of failure grows every month. The second is regulatory pressure: KVKK (Türkiye's personal data protection law), BDDK (Banking Regulation and Supervision Agency) rules and healthcare legislation require you to document where data is and how it is protected, which is not possible in a server room with no air conditioning. The third is business continuity: any single-site infrastructure in an earthquake zone is a single point of failure. A cloud migration solves all three problems in one project.
DataKobi has provided cloud services in Türkiye since 2014; today, the production workloads of more than 200 organizations run in our Ankara (ESB-DC1) and Istanbul (IST-DC2) data centers. From production lines to hospital image archives, from holding company ERPs to e-commerce platforms, we have completed hundreds of migration projects without downtime. The simulation above is not a metaphor but a visualization of our actual methodology: each sector's data flows through its own encrypted tunnel, using its own protocol.
How a cloud migration unfolds, step by step.
Our methodology has six phases, and the output of each phase is documented in writing. Projects fail not because of technology but because of skipped discovery and untested rollback plans, which is why we spend a third of the total time on the first two phases.
Discovery and inventory
Your servers, applications, databases and the dependencies between them are mapped with automated tools and engineer interviews. Output: the resource requirements, dependency graph and risk note for every system to be migrated.
Planning and tiering
Systems are split into waves by criticality: low-risk workloads first, the core ERP/database last. For each wave, the downtime window, owners and rollback plan are agreed in writing.
Target environment build
A twin of your network is built in the DataKobi data center: VLANs, firewall rules, VPN tunnels and backup policies are ready and tested before anything goes into production.
Live synchronization
Data is copied in the background over encrypted tunnels; block-level replication and CDC keep the target continuously up to date while the source system keeps running. Downtime in this phase is zero.
Rehearsal and final cutover
A go-live rehearsal is run in an isolated network, and your business units validate the applications. At the final cutover, only the last changes are transferred and DNS/IP is switched; typical downtime is a matter of minutes.
Hypercare period
For 30 days after the cutover, the environment is closely monitored: performance comparison, cost tuning (rightsizing) and team training are completed in this period. The old environment is kept until you approve its decommissioning.
Every sector's data flows differently.
"Copy the data" means three different engineering problems in a factory, a holding company and a hospital. We build the migration plan around the character of your sector's data:
Manufacturing and factory data
Telemetry streaming from sensors and PLCs on the shop floor is routed to a time-series database in the cloud through MQTT/OPC-UA bridges; MES and quality data are moved with block replication. The production line never stops: at cutover, only the data write target changes. Production data moved to the cloud is also ready for OEE dashboards and predictive maintenance analytics.
Holding companies and enterprise systems
ERP and accounting databases are synchronized live with CDC (change data capture): every transaction on the source side is applied to the cloud replica within seconds. File servers and email archives are moved in a parallel stream. Group companies are split into waves one by one; your consolidation reports keep running throughout the cutover.
Healthcare and hospital data
Image archives (PACS/DICOM) take up terabytes, and patient data is classed as 'special category' under KVKK. The transfer runs over an end-to-end encrypted DICOM stream with access logs kept; HL7/FHIR integrations are rebuilt one-to-one in the target. Data never leaves our facilities in Türkiye, so the domestic-hosting requirement of healthcare regulations is fully met.
How is your data protected during the migration?
The most sensitive moment of a migration is when data is in transit between two facilities. That is why there is no compromise at the transfer layer: each sector's traffic flows inside its own IPSec tunnel, encrypted with AES-256; key exchange uses modern standards (IKEv2), and the data is never opened at any intermediate point. Every transferred block is compared against the checksum at the source: data we call "migrated" is data verified at the bit level.
Protection continues on the target side: at-rest disk encryption, network segmentation, daily backups and animmutable copy against ransomware are in place from day one. Who accessed our systems during the migration, when, and which data they touched is logged, and these logs go into your KVKK audit file. If you wish, before the final cutover we can carry out an on-site verification together with your security team or your independent auditor.
After the move: managed cloud.
Migration is half the story. Once your data is with DataKobi, it runs in a managed cloudmodel with 24/7 staffed NOC monitoring, daily backups, security layers and a contractual 99.99% SLA. The console below is a simulation of the screen our team watches every day:
Why DataKobi data center services?
Choosing a data center is a ten-year decision and should be judged on four criteria. Physical infrastructure: our facilities are built to Uptime Institute Tier III design principles, with 2N power redundancy, N+1 cooling, fire suppression and 24/7 physical security. Geographic redundancy: our Ankara and Istanbul locations are connected by a private fiber backbone, and your disaster recovery scenario is set up under the same contract. Regulation: we are ISO 27001 certified, we commit to KVKK requirements by contract, and on-site audits are standard for customers subject to regulation. People: on the support line you reach not a call center reading from scripts but engineers who know your systems; the first-response target for critical requests is 15 minutes.
On the cost side, the arithmetic is transparent: a fixed monthly price in TL, zero fees on data egress, no exchange-rate surprises. In the discovery report, we put your current hardware depreciation, licensing, energy, cooling and staff costs side by side with the cloud subscription; for customers who have moved to the cloud, a first-year total cost of ownership saving of 35-45% has typically been measured. The decision is yours; we simply put the numbers on the table.
What should you prepare before the discovery meeting?
Discovery goes ahead even if you prepare nothing; but if you have the six items below to hand, a draft plan comes out of the first meeting and the project gains weeks. Most of our customers complete this list with their IT lead in a single afternoon:
Server inventory
A list of your physical and virtual servers: operating system, CPU/RAM/disk, age and the application running on each. It does not need to be complete; our discovery tools fill in the gaps.
Critical application list
Which applications bring your business to a halt when they stop? ERP, email, production software... For each one, ask your business units for the 'acceptable downtime'; the wave plan is built around it.
Data volumes
Database sizes, the file server total, the email archive and, if you have one, the image archive (PACS) volume. Synchronization time and line capacity are calculated from these figures.
Current network diagram
Your internet line capacity, firewall model, VPN usage and connections between locations. Even a hand-drawn diagram speeds up building the network twin.
License inventory
Your Windows Server, SQL Server, virtualization and backup licenses. Some can be brought to the cloud (BYOL), while for others monthly rental is more economical; we work out the numbers together.
Compliance requirements
The regulations you are subject to: your KVKK inventory, your ISO 27001 scope, sector-specific audit requirements. The contract and the audit file are prepared around these requirements.
