SEP 12.11 - 64bit GUP - can it pass defs to 32bit clients?

Hi,

We use GUP's extensively and are plamnning to move to 12.2 shortly.

Currently the GUP is the same OS type and edition and the clients that update from it - 32bit operating system.

We are starting to put in 64bit clients, will these get defintiions from the GUPs or do I need to configure something or install a 64bit GUP?

Also can the opposite work?  If I put in a 64bit GUP in, can it update both 64 and 32bit gups?

Thanks
