This is exactly what used to happen for SONAR (and CWPA before that) upgrades to new versions.
(that's why SPLAT was great, because we didn't have ot do this every year...)
You just have to go through the paths, and copy things like templates, plugin menus, FX chains, customised rum maps etc etc to the new folders - or else point the new version to the old folders.
This is not anything new...
