Hello Team

I have some questions :
1°) I need your help, to find the better way to upgrade my 3 servers linked (replicat).
I want to upgrade servers from CentOS 7.6 to CentOS7.7 with update in same time the IPAServer (or separately ?)

After searching on Freeipa.org and other site, i find :
#ipactl stop
#ipa-server-upgrade
#ipactl start

I not need to delete first the replication link before ?
What is the better solution ways ?

2°) Is not better to migrate my IPAServers's to 4.7 or 4.8 version ?
Or i need steps too ?

Thanks you for your help

Best Regard
Bien à vous
