    Umbraco database migration stuck

    Hi, I'm trying to update my Umbraco site from 7.14 to 8.1.1, I use this guide. It doesn't get past

    Upgrading Umbraco to the latest and greatest version.

    I have waited for over an hour but nothing changes. I've looked in my log and there are not coming any new lines. The last few lines in my logs are like this for a few thousand lines, i can't find any errors!

    Is there someone who can help me fix this?

    How many rows do you have in the cmsPropertyData table? The next step in the migration is to update each row to fill in the versionId2 column that was just created, and you won't see anything in the log until that finishes. This step scales rather poorly when there are a lot of rows.

    If you're feeling brave, I have a modified version of the Umbraco.Core.dll for 8.1.4 here which speeds up the migration significantly (hopefully without breaking anything). If you want to test it, I'd appreciate a copy of the log file so that I can see how it performs and where there may be more room for improvement.
