back again.
pointed my wrye mash shortcut to the new install, so now that's recognizing my mod list there and my saves. i updated any of my bad esps and synced my save in mash, so getting closer. when i start up the save, i get a bunch of errors, listed below from my warnings...

i recognize the beginning of that as a bunch of dialogue from the temple, and have no idea why it would be affected. these still come up after selecting repair all in wrye mash. if i click through them, the save seems fine. saved in a new slot and these went away, so i'm not sure how much they matter. going to move my other saves and sync them too, i guess.
the only remaining questions then, are if i need to care about the errors above and what to do with the old install.
