Hey Folks,
I'm looking into migrating my FreeIPA 4.6.6 setup to RHEL 9 or any of
the subject *nix 9 environments.
The immediate steps I can see doing is:
0) Take snapshots
1) Spin up RHEL 9 or Cent OS 9 boxes etc.
2) Install the latest FreeIPA version.
3) Enable replication from the older RHEL 7 FreeIPA 4.6.6 installation
to this newer installation. (Possible?)
4) Decomm old nodes or rebuild with latest *nix 9.X image.
5) Rinse and repeat till all done.
For step 3) is it even possible to migrate from an older FreeIPA
version to a newer one? Any known issues? Should I target the
install on the *nix 9 hosts to the exact same version as FreeIPA on
RHEL 7 nodes?
Start here:

Direct migration from RHEL 7 to RHEL 9 version of RHEL IdM might not be
possible due to tightened crypto system on RHEL 9.
