Anyone have issues using PDM 2019 with SW2018?

Hi everyone, I was going to update my license server and vaults and archive server to PDM Standard 2019.  My plan is to keep my users on 2018 until I've done some testing on 2019 and established that it won't break our workflows.

On paper (or the online manual) it looks like SW2018 will talk to a 2019 vault and license server.

Has anyone tried this and run into problems?
