swing migration Enterprise manager or VBR first?

[SSSSSStorage]

Hi everyone,

We need to move our Enterprise Manager and B&R servers off server 2016 to server 2022, ive read up on the migration options and think i understand the process of importing the config and pointing back to our DBs. the main question I have is about the correct order.

In the past for upgrades we have always done EM first, and our B&R server pulls its license from EM. If we move EM, will that continue to license the orginal B&R server, or will it temporarily become unlicensed and cause any issues? I aim to do the work on the same day ideally.

I had planned to do the below
1) disable all jobs
2) swing migration of EM 2016 > 2022
3) swing migration of B&R 2016 > 2022
4) check all infrastructure etc...
5) slowly start checking jobs

anyone aware of any gotchas?
