I have a MacMini (2011, running Sierra) that's happily running my house, and has been for some time. I keep it as up to date as I can, but it's running Sierra for the Server.
I have a MacBook Pro that I use for client connections that I'd like to update to BigSur if I can.
Has anybody tried this and has warnings about upgrading the client side? I won't touch the Mini (it wouldn't run later OS's anyway), but would like to upgrade the MBP.. If it comes down to it, I can control it using TeamViewer and just removing the client app on the MBP.
TIA for comments/advice.
Steve
