I'm trying to update an older site from 7.2.1 to 7.10.4 (the latest version when I'm writing this). I'm updated the NuGet package, and the resulting config files seem fine. I'm able to run the site (through IIS), and I am redirected to the Authorize Upgrade page as expected.
But from there I cannot log in. On the page, I get the message Login failed for user [email protected]. Below is what appears in the log. The issue appears to be related to the umbracoUser2UserGroup table which is not in the database. My guess is that the installer would add it, but as I cannot log in, it cannot be added. And so I'm stuck.
Here's what I have checked so far:
useLegacyEncoding is true for both UmbracoMembershipProvider and UsersMembershipProvider. Changing it to false does not help.
My connection string is valid and the database user has full permissions over the database (it can create/drop tables). I'm using SQL Server.
The user record in the umbracoUser table is fine. It is not disabled, neither is userNoConsole set to true.
I am able to log in using that user before updating the NuGet package.
Umbraco Forms is installed and needs updated, too. It was at version 4.0.0 and has also been updated through NuGet to 7.0.2. At both versions, the Authorize Upgrade Login failed.
AppPools have been recycled, the site has been restarted, caches and cookies cleared multiple times.

I have not solved this issue yet, but I do have some more insight. I created a blank site and installed 7.2.1 on it. I ran it to verify that it was all good, then updated to 7.10.4 through NuGet. I got the same error when trying to log in to authorize the installer to perform the database updates. The error messages in the log are the same.
I'm going to try to do the upgrade in smaller increments (7.2 to 7.3 then 7.4, etc) now to see if that can get me around the issue.
