I'm testing a 1.7.53.3 migration to version 2.1 (or whatever version the migration plugin uses). I ran into one problem, which I previously posted about, in that of the 5 directory trees in side user/pages, only one got copied to grav-2. I manually copied the whole tree and did my testing and everything looks okay. So I went to the 'promote' step.
It's in the 'creating a timestamped backup' step and it says it backed up 11,000 files and is currently on
backup — system/src/Twig/DeferredExtension/DeferredNodeVisitorCompat.php
And it's stopped there. This is the second attempt. The first time, after waiting for 30 minutes to see if it was going to go any farther, my laptop crashed (unrelated to the migration). I went back in and resumed the migration and it stopped at the same place again.
I'm using NGINX on this site. Any ideas?
