Reconnecting Synths (DimPro) to XI projects

Having some difficulty opening 8.5 projects on new PC build with X1 Producer.
Quite a few synths are still loaded in the Synth rack but disconnected/offline. I know I did not install the new synths, like Dimpro in the same path
as 8.5 projects, so obviously Sonar has no way to finding it I guess......any workarounds/tricks to restore the relationships, short off duplicating
the exact install paths from 8.5?
And one tip from me.....limit your 3rd party plug-in use....I cannot begin to describe the time and effort it took/still takes to install all those seductive
free effects/synths/etc, from around the web I amassed throughout the years....what a jerk I be...
Thanks for the help in advance.
