Thanks for the prompt response James.
I was asking about the GUP . Can RU2 GUP server content to RU4 endpoints. You are telling about the SEPM support for older version GUPs
Secondly its a best practice to upgrad GUP first , but is it mandatory to update GUP first than endpoints ?
meaning for some reasons If GUP weren't updated first than clients then would clients stop taking updates from the GUP since GUP is on a lower version ?
thanks and regards
