Hi there, thank you for using Gogs for so long!
However, Gogs has stopped supporting auto-migration from your previously installed version.
But the good news is, it's very easy to fix this problem!
You can migrate your older database using a previous release, then you can upgrade to the newest version.
Please save following instructions to somewhere and start working:
- If you were using below 0.6.0 (e.g. 0.5.x), download last supported archive from following link:
https://github.com/gogs/gogs/releases/tag/v0.7.33
- If you were using below 0.7.0 (e.g. 0.6.x), download last supported archive from following link:
https://github.com/gogs/gogs/releases/tag/v0.9.141
Once finished downloading,
1. Extract the archive and to upgrade steps as usual.
2. Run it once. To verify, you should see some migration traces.
3. Once it starts web server successfully, stop it.
4. Now it's time to put back the release archive you originally intent to upgrade.
5. Enjoy!
In case you're stilling getting this notice, go through instructions again until it disappears.`)
