Upgrade older projects with ProQ4
What is the best way to upgrade all my instances of PQ3 to PQ4 in older projects?
Long term it might not be practical to keep installing PQ3 for backward compatibility.
The only way I can think of is very manual (save everything as a preset, load preset in PQ4). It could be days of work and I will end up forgetting something :)

BTW, I am aware of: www.fabfilter.com/help/pro-q/support/upgrading#:~:text=First%2C%20save%20the%20current%20setting,submenu%20in%20the%20preset%20menu.
That is essentially what I mean with "save everything as a preset, load preset in PQ4".
I see the issue with automation, yeah. So probably there will never be a fully automated way to do so.
At this moment it's not possible to automatically replace instances of Pro-Q 3 with Pro-Q 4. We're actively in touch with the developers of VST3, AU, AAX and CLAP to make this possible in the future.
