I found some good information about migrating from 3.3 to 4.x using replica's.
It's not 100% clear what I can do on a CentOS 6.6 install with 3.0 as
CentOS doesn't provide 3.3.
Some other question is that my hostnames are now like ipa-01 and
ipa-02 where I make one replica ipa-01-1 and finally go from there.
But what is the best way to set my hostnames back to ipa-01 from
ipa-01-1 (and maybe ipa-02-1) ?
I hope for some good suggestions.
You can't change a hostname in IPA. You'd need to create ipa-01-1 and
ipa-02-1, confirm that they are working ok, delete ipa-01 and ipa-02,
then re-create those as new replicas, connect them, then delete the -1
versions. It is a lot of trouble to go through to preserve a hostname.
Things to consider:
- maintaining a CA throughout
- consider DNA ranges
- ensure that RUVs are properly cleaned up
