You thought it was over and that we would go straight to the migration? Well, not quite! I still have a few things to say and share with you before: my final tips and best practices based on my experience!

Careful preparation

The first and I think most important advice I can give you is to prepare your migration well. List your virtual machines, identify the installed operating systems, check that they are up to date and that the migration prerequisites are met…

It takes time, but it is the key to a successful migration every time.

Measured migration plans

My second piece of advice is to create migration plans of a reasonable size. If the software limit can go up to 100 virtual machines per migration plan, I would advise you to limit yourself to a maximum of twenty machines.

This allows you to better manage your migration, to have fewer potential errors to manage and to be able to correct problems more quickly if you encounter them once the virtual machines have been switched over and to limit the risk of prolonged service interruption.

Homogeneous migration plans

As far as possible, try to create migration plans grouping virtual machines that are similar in terms of operating system. Again, in the event of a problem during the migration, it will always be easier to look for a common error on several servers with the same operating system than between disparate servers.

Take your time

Above all, do not rush! It is better to take your time and make a smooth migration, rather than rushing, encountering problems, being forced to backtrack, etc. Take the time to build your migration plans, to prepare them well, to configure them in their smallest details so that they go smoothly.

Some good practices to follow

Here are some good practices to follow that will allow you to avoid a certain number of inconveniences. There are probably others that I have not mentioned but this already constitutes a solid base:

• Check the compatibility of your operating systems.

• Check that all the prerequisites are respected upstream.

• Check that your clusters can communicate with each other.

• Stop the backup jobs before starting your migrations.

If in doubt, refer to the official documentation: https://portal.nutanix.com/page/documents/details?targetId=Nutanix-Move-v5_4:Nutanix-Move-v5_4

Now, you are ready to finalize the migration of your virtual machines…
