Replace Mangement Server *NIX monitoring

I’m replacing the 2012 management servers in my SCOM2016 management group with server 2019, so that I can then in-place upgrade to SCOM2019. I’m doing this one at a time by removing the management server from SCOM, deleting the VM, then setting a new one up with the same name and IP and adding it back to the 2016 management group.

I’ve done the easy ones, now I need to tackle the two that make up my *NIX monitoring resource pool. If I replace one of the two servers in the resource pool then copy its new certificate to the existing second member (and vice versa) will that maintain *NIX monitoring whilst I then do the same thing to the second server? For example:

Existing *NIX Resource Pool (SCOM2016 MG):
SCOMMS1 - server 2012
SCOMMS2 - server 2012

goes to:

SCOMMS1 - server 2019
SCOMMS2 - server 2012
copy certificates both ways

then to:

SCOMMS1 - server 2019
SCOMMS2 - server 2019
copy certificates both ways

Will that work? Or is there a better way?
