reinstalled the OS, best way to migrate Syncthing?

Thanks @imsodin , data is indeed unchanged & at same path.

Something did not go as expected…

On 1 side of the sync, 2376 items across 3 Folders are stuck “out of sync” this number isn’t changing. This is the host that has remained untouched.

On the other host, which got a fresh OS on the C drive, 1 item remains stuck “out of sync”.

This seems eerily similar to Out of sync items are incorrect and not syncing , but setting “ignore permissions” hasn’t helped. (I tried the option on the host with just the 1 out-of-sync.)

Help ?
