PT11.3.2, OSX 10.10.5 & Waves 9.91

As some here might know or remember I used to run 3 boot partitions (OSX 10.8.5, OSX 10.9.5 and OSX 10.10.2). The latter was too unstable for production work so I deleted it. This was way before I heavily got into Waves plugins. Now let's just say I have a few of them. I have the latest versions that will run in PT11.3.2 and OSX 10.9.5. For certain reasons I just re-added a third boot partition with OSX 10.10.5. Checking for plugin updates Waves Central tells me there's a bunch of updates for all my plugins. Before I pull the trigger on the updates I need to know how badly will PT11.3.2 bitch at me if I work on a session in Yosemite and go back into it in Mavericks?

I suspect I'll get a bunch of error messages but I should be able to at least call up the old ones in the Mavericks partition right? I know about making presets for any settings and using them so that's not the issue. Or will I have to open the session in safe mode and if I do that can I still somehow access the plugin settings? I imagine not on the latter.

This will only be an issue until I get comfortable with working inside Yosemite and not have to go back to Mavericks.
