[Issue]: Starting freshly installed Jellyfin server for the second time fails with MigrateNetworkConfiguration error

[Sky-High]

Please describe your bug

After recent Jellyfin.Networking updates, running a freshly installed Jellyfin server (i.e. no configuration files in AppData\Local\jellyfin) logs 'CreateNetworkConfiguration' in AppData\Local\jellyfin\config\migrations.xml.

Starting Jellyfin server for the second time, however, checks for 'MigrateNetworkConfiguration' in migrations.xml, which isn't there, causing Jellyfin server to abort with an error and stacktrace.

Jellyfin Version

if other:

10.9.0

Probably has something to do with this change last week:

or one of the other ones that day.

Yeah, the issue probably existed already earlier but indeed became only apparent after those changes.

Interested to know if the PR fixes your issue too.

[Paulus88]

I normally pull it from: https://repo.jellyfin.org/releases/server/windows/versions/unstable/combined/

Is this considered the PR version?

[Sky-High]

The changes in the PR have not been merged yet, so you can wait for that.
Or you apply the changes manually, of course.
See PR #9987

Thanks @Sky-High, I'm not that good at C# will probably look into it in the near future as it seems to be the language all modern apps are using, Ill wait for your fix to be added to the release. Reading the PR it seems to match my issue exactly.
Always have great respect for you guys working hard on this app

[Paulus88]

Thanks to your explination in #9987 I managed to get a workaround setup and have my Jellyfin back yeeey, I can't wait until they get your patch as its a lot of messing with network.xml and metadata.xml. I will be watching your patch closely when its accepted.
