[Samba] Upgrading from 4.6.x to 4.7.x AD and member server setup - recommended path
Hi, we have three 4.6.x AD servers in a cluster and some member Fileservers. What is the best/savest/recomended upgrade path? Can I upgrade the AD servers one by one and run a „mixed“ setup for some time (minutes) ? Or do I have to shutdown/disable two of them first, then update the one still up and running and than updates the others? Thanks for hints and suggestion! Regards . Götz

If you are going to compile Samba yourself, you will need to use the configure options as originally and stop Samba before running 'make install'. Either way, I would start with the DC holding all the FSMO roles. Then the other two DCs, one by one. Rowland

I did find something in the samba wiki as I had time to google, which says the other way round; starting with a server that dose NOT hols a FSMO. https://wiki.samba.org/index.php/Updating_Samba#Updating_Multiple_Samba_Domain_Controllers <https://wiki.samba.org/index.php/Updating_Samba#Updating_Multiple_Samba_Domain_Controllers> If you are updating multiple Samba Active Directory (AD) Domain Controllers (DC), the recommended order is: Update one Samba AD DC that does not hold any flexible single master operations (FSMO) role. So thats the way to go ? And dose all DCs should be shut down at that time? Regards . Götz
