Raising the Functional Levels in ucs@school domain to 2012_r2

Hello,

a colleague has asked me to increase the functionality level of the samba domain in our ucs@school domain to the maximum value (due to GPO requirements).
According to https://wiki.samba.org/index.php/Raising_the_Functional_Levels i can go up to 2012_r2.

Now the questions:

  • Does this have side effects?
  • Do I have to do it only on the master, backup and also on every school slave? Maybe the change will be synced via S4…

Thank you very much
