In this case, we will share how SIM-Networks specialists managed to carry out a full infrastructure migration for a medium-sized company in 3 business days.
What were the client’s expectations from the migration?
The client is an FMCG company with approximately 250 employees. By the time the project had started, the company’s IT infrastructure consisted of 7 local physical servers with virtualization. The company’s owners have decided to migrate the data into a data center in Europe. The data center in Germany, where SIM-Networks hosts its infrastructure, meets high data security standards. The company expected to retain flexibility in terms of infrastructure management, as well as full support during the migration process.
The cloud migration had to be carried out solely by SIM-Networks’ in-house specialists. The total volume of data that had to be transferred was 25 TB. While reviewing the documentation, we discovered that the infrastructure was modernized in multiple stages: new services were added, new resources were rented and employees came and left.
The IT infrastructure modernization was carried out without proper documentation. The client did not have an accurate description of the network topology, including the IP addresses of all nodes. Some questions posed by our consultants during the pre-project evaluation were left unanswered – no one in the client’s team had definitive answers. The client also requested that the migration be carried out covertly.
- migrate the virtual & physical servers into the cloud with a few drives each: a file server, 2 data base servers and a connection broker;
- set up a network connection between the instances and set up the VPN SSTP protocol;
- organize reserve data copying using BaaS (Backup-as-a-Service).
