Change of Data Center provider
Scale: Company with over 40,000 employees worldwide
Project duration: 3 years
ITR-GROUP joined in B2B mode, as one of the suppliers of know-how and resources.
The project concerned the transfer of the client’s entire huge IT infrastructure from the current Datacenter CMO (Current Mode of Operation) to the new Datacenter FMO (Future Mode of Operation) delivered by another provider.
The scale of the project itself was enormous:
- ca. 200 people involved in the project from the FMO supplier
- ca. 200 people involved on the client’s side alone
- ca. 50 people delegated by the CMO provider
Total of 1000 applications
Europe’s largest installation in Microsoft BI environment
- In the first phase, ITR-GROUP supported the definition of the scope of the project – which applications are transferable, which technologies they are based on, how many servers they use.
- Then the contractual rules of cooperation between the parties involved were defined (ITR GROUP helped to define them and audit the contract):
– CMO provider
– FMO provider
– 3rd-Parties: IBM, ATOS, ACCENTURE, DELLOITE etc.
- ITR-GROUP IT specialists were involved in the physical migration phase in the following areas:
– End-2-End Project Management
– Technical Transition Management
– MS SQL, Oracle, AWS DB, AZURE
– Unix, Linux, Solaris Systems
– Microsoft BI Solutions
- We planned carefully and coordinated the GO-LIVE migrations according to the client’s guidelines and CMO and FMO conditions
We created RUN-books, cutover plans and all necessary documentation
We managed particular technical resources, giving them appropriate instructions and permissions to go through the next technical migration steps
It is worth mentioning the very meticulous documentation produced by ITR-GROUP at the request of individual parties (counterparts):
Requested UAT test results
Criteria for system acceptance after migration
Under the supervision and with the participation of the ITR-GROUP 60 large, complex heterogeneous applications were successfully migrated.
Scale: Company with over 100,000 employees worldwide. IT alone is made up of tens of thousands of employees dispersed around the world.
Project duration: 3-4 years
We were asked, as an OUTSOURCING partner, to support a huge CARVE-OUT project. This term refers to the separation of the subsidiary from the parent company. This has, above all, major stock market consequences. However, the regulator also describes the IT procedures that have to be fulfilled in order for this process to be considered successful.
This is also a logical separation of the IT infrastructure in such a way that its components are not accessible to each other via LAN connections after CARVE-OUT (only WAN traffic is allowed). This potentially simple task is, in effect, a large and extensive project.
In the first phase ITR-Group supported the client in defining the project scope:
Which systems will be covered by the project
Where to migrate to: own DataCenter, cloud solutions: AWS, AZURE, GC, OCI etc.
Then we supported the architecture design phase:
Description of current systems
Where and how they will be migrated
The third phase concerned the preparation and execution of migration:
Planning and preparing hundreds of conversations with application owners
Recording results and analysing their impact on further project development
Migration planning with the technical teams responsible for their implementation
Supervising migration in all necessary environments:
Current state of affairs – the project has been planned for 3 years. The company has been involved in it for one year. The project is still ongoing.
Migration from Solaris to Linux
Scale: A well-known big bank
Project duration: 2 years
ITR-Group has made several such projects in its career. Here we will focus on describing one of them.
As an external competency provider, ITR-Group was asked to:
conduct the Due-Dilligence phase
prepare a cost estimation
analyse the feasibility phase
estimate the project duration
Entering the project:
Of course we started with the feasibility stage and the key points important for our client. The banking environment is characterized by a very high level of redundancy and particular attention to security. These aspects make the project more complicated and time-consuming.
In this particular case, we have defined about 30 services, using more than 100 servers in total, mainly in Solaris environment and using Oracle database technology.
The goal of the project was to migrate them to the Linux environment.
Definition of risk
Interviews with application owners to estimate the level of complexity and additional costs from external software providers
Go-LIVEs planning with DC supplier and application owner and developer
Through coordinated activities, a good description of the scope and costs, the project was successfully completed.
At the ITR Group, we face up to current technological trends and advise our customers on how they can safely and effectively go through the IT transformation process according to current standards.
Customer comes first
Our focus is always on the customer. Regardless of the industry or application used. Of course there are areas where a specific experience with a particular application is essential.
Years of experience
As an experienced IT partner, we are able to quickly estimate how long and complex a given migration project will be and provide appropriate resources for its implementation.
ITR-GROUP is a young company, established in 2019. However, its founders have over 20 years of experience in the IT industry. We started our adventure in the FMCG industry by planning LAN and WAN networks, creating Data Center architecture for our customers. Then, along with the evolution of the IT sector, we led our clients through individual stages of Data Center migration and transformation.
