Migration of data center isn’t done daily, and if you are planning for one in-house then you should make sure that you are not making these mistakes for sure:
Mistake 1: You are in a hurry, and you didn’t perform a proper assessment.
If you have not taken detailed account of what you have in your data center, then you are preparing a recipe for failure. Instead, this should be the starting point. Ask these questions to make sure that you checked things:
- How many physical loads are there?
- How many are virtual?
- Which data is stored locally?
- Check out the workloads on shared storage
Once you have a clear list of all such workloads, you will have to figure out how they will be moved to the new environment. In this way you will have clear idea of what infrastructure you may need and how much budget should you have for it?
Mistake 2: You ignored dependencies
Taking account of the part of your legacy data center is just a start. More important is a blueprint of the working system. And you will be able to make one when you clearly understand how the existing system is stacked up. And not just hardware, you have to be clear with various applications and their usage of the database. To this end, you need to have a complete and up-to-date application dependency map before you think of making the data center migration.
Tip: Prepare and blueprint with dependency details of hardware and software.
Mistake 3: You don’t consider it as a project
Are you migrating a single server from one location to the other? It’s simple, and any person with little technical know-how will be able to do it. But things are not so simple when you are migrating a data-center. He has skills and the most importantly the experience of managing projects of any scale. He may be a person who can take the complete responsibility of the project and guide the team in the challenging time.
Mistake 4: Not Having a Documented Project Plan
Do you want your team to spend nights over technical issues that cropped up? Do you have a comprehensive project execution plan that can take care of the data center migration in a scheduled manner? A project plan comes with a detailed schedule and assigns responsibilities to team members. The project plan also delineates technical procedures that act as guides for the entire team. In the absence of such detailed documented procedure your team might be working, but they may not be able to meet all the deliverables in a stipulated time.
Tip: Make sure that project schedule and documents are well in place.
Mistake 5: Making assumptions about equipment occupancy
Data center usually consists of bulky equipment, and you have to make sure that all the equipment fits perfectly in the planned new space. You will have to ensure that all the large equipment can clear all the corners, can reach the elevator. You will have to make sure that all of them are large enough and are working when you plan to move them.
Tip: It is a good idea to measure the equipment and its sizes and also the path through which it will pass. In this way, you and your team can expect to face fewer hassles in moving the equipment.
Mistake 6: Not Having Enough Time to Make Things Happen
As stated earlier, you might be prepared with a project schedule. But if you try to squeeze the schedule and pack too many things or expect results too early, then you are probably making the biggest mistake. If you faced any minor glitch during the transfer of the equipment or the during the installation of the new equipment, then you are sure to see your schedule going haywire. While making schedule you have to take into account the overheads as well. Bear in mind that your teams get tired as well. A miscalculation in scheduling by the team may add to the business downtime. And as a result, the entire project cost may go up significantly. It may also raise a question mark on the entire process as well.
Tip: Include time for overheads and unforeseen events.
Mistake 7: There is not test-plan
In small projects, you can do with the no-test plan. But for large-scale projects, you need to have a proper test plan in place. It will make sure that all data-center migration project is successful and all the deliverables have been met.
Mistake 8: Making assumptions about completion
If you think that you have completed the project successfully, then you will have to verify every application in the new environment.
You forgot to have a support team after completion of the data-center migration project. It may give troubles to your team who are trying to adjust to new environment.
