Upgrading VMM 2016 to 2019 - ASR Redeployment

Hi there,

I'm looking at upgrading our VMM from 2016 to 2019, and I've been looking at an article that states:


If your current VMM deployment is integrated with Azure Site Recovery, note that:
  • Site Recovery settings can't be upgraded. After the upgrade you need to redeploy.
  • Verify Hyper-V host support for VMM 2019.

I read this as needing to set up ASR again completely; just wanted to check that this is the case.

Will ASR stop working after an upgrade to VMM 2019, and need to be set up again?

If anyone has completed the upgrade to VMM 2019 themselves, and uses ASR, I'd be grateful to hear what was involved in terms of redeploying ASR.

Upgrading VMM version shouldn’t impact ongoing replications provided the VMM Server’s Operating System isn’t changed.

Hello Sadiqh,

Thanks for your reply.

In that case, if the VMM server's OS was upgraded, am I right in thinking we would need to set up ASR again for all servers managed by that VMM server?

We are looking to upgrade the OS as well. (from 2016 to 2019)

Upgrading OS might break replication. If that happens you need to re-enable replication.
