Harmony 11 and 12 compatibility

Are version 11 and 12 compatible?
If you don’t use any effects only available in version 12, could you use both versions with the same scenes without problems?

(Version 12 at home. Version 11 at work.)

Thanks!

Aside from exclusive effects, some preexisting features have been reworked. I don’t think it will be so easy as avoiding exclusive effects. You may see aberrations and need to track down their source to resolve problems or you may be lucky and not see any problems.

deformers for example have been reworked from 11 to 12, and even within the builds of 12
