Sorta. Not sure If I should purge the mods, though. I have enough space on the portable HDD to just copy everything. My biggets worry is this though:
If I follow these steps and then delete everything on the SSD, Vortex is probably going to report any number of errors, even after following this guide. However I'd still like to use it for modding Skyrim instead of just leaving it unused until playing Fallout 4 again. Anyway thanks for the help, that should cover the most important steps at any rate.
