Exchange 2016 cu 19 & compatibility with Exchange 2010

Copper Contributor

Customer is going through an exchange migration in a 2016/2010 coexistence upgrade.   Didn't get 2016 patched in time for the Zero Day exploits & want to apply the patches, but I need to move them from cu16 to cu19 & they still have about 1/2 the mailboxes on 2010.


Little concern the AD/Forrest scheme changes might impact 2010

I going to assume since 2010 is EOL... there is going to be no support for 2010.  (it's on the latest 2010 cu)

Any ideas or someone experience otherwise?
