I recently did a bare metal migration from Gitea to Forgejo using NixOS, maybe this info is useful if you use SQLite (which I believe is the default): the SQLite database filename for Gitea is gitea.db and for Forgejo it’s forgejo.db so I had to do a rename. Before renaming I ended up with an empty Forgejo instance. Either way I hope you figure it out in the end. Good luck!

Thanks, I'll try that.
Unfortunately that didn't work for me.
Why this backwards way of migrating? The recommended way to to replace the Gitea docker image with the Forgejo one and leave everything else in place. Maybe make a backup before that you can revert to in case something goes wrong though.
What are you using as a database? Also, from which Gitea version to which Forgejo version did you attempt the migration?
Both gitea and forgejo are using sqlite3. Gitea 1.20.0, Forgejo 1.21.
Can you see the data you copied inside the container? I’m quite sure you either don’t have the volume mounted, or the config files refers to a different folder than the gitea one did. Did your gitea container store data in sqlite as you are copying raw files rather than migrating a database?
I’d go with lxc instead of containers if you don’t fully understand docker. Overhead isn’t much different and you get a “normal server” where you can drop in forgejo to replace gitea
Can you see the data you copied inside the container?
That led me to my problem! I did have the volume mounted, but the container's path was incorrect: Forgejo was recreating it's resource files as a new install because where it was looking for them, they didn't exist.
Thanks!
Why migrate from gitea to forgejo?
Thx! Will prob migrate as well!!
No experience, but saw gorgeous has a guide to migrate. Their latest Blogpost states to do that ASAP coz they're going to stop keeping the drop-in 1:1 replacement to advance in their cool feature set ;)
Okay so your post inspired me to make the switch. All I had to do was switch out the image to the forgejo one. Everything worked right away. To try to make things as clean as possible, I went ahead and renamed my bind volume paths and app.ini stuff from gitea to forgejo but no matter what I tried, once I started the container, the container would create a gitea directory with a new app.ini. I even tried to run the forgejo compose on another host and the app still creates a gitea directory within the bind mount. Am I doing something wrong. I understand it’s a drop in replacement but I’m sure there’s a way to get a cleaner cut over.
compose.yml
volumes:
- ./data:/data
Host directories
~/forgejo
- data - forgejo - renamed for the migration - git - ssh - gitea - gets created by the app no matter what I do or what paths are set in app.ini
- compose.yml
How do I keep forgejo from creating this gitea directory? Why doesn’t it create a forgejo directory???
Edit: gitea version was - 1.21.7 and forgejo replacement image is 1.21.7-0
I don't know if your problem is the same as mine was, but the symptom sounds the same.
The docker-compose.yaml file shown in the Forgejo documentation for docker installation shows this mount:
volumes:
- ./forgejo:/data
For me, Forgejo installed and created new resource files in /data and ignored the resource files gitea alread made.
I changed the volume to:
volumes:
- data:/var/lib/gitea
Forgejo then recognized the gitea resources.
Not quiet. I was running gitea before so my mount was ./gitea:/data but since switching over to forgejo, I renamed my ./gitea directory to ./forgejo. Adjusted my compose file to have a mount of ./forgejo:/data.
Now inside of that renamed forgejo directory, there are a bunch of gitea references and even one more directory called gitea. When I migrated everything worked right away but since I wanted a cleaner transition, I renamed and switched all gitea references to forgejo but went I brought the stack back online, it went belly up.
As a troubleshooting step, I recreated my compose file and created a new empty ./forgejo on a different machine just to see what a new and fresh install would look like and the forgejo stack itself created all kinds of gitea references and gitea directory once I brought it up. So to fix my original deployment, I reverted all the references back from forgejo to gitea and everything worked again.
For fun, I went out to codeberg to look at the Dockerfile and saw that they had a bunch of gitea things within their own Dockerfile so nothing I can do for now
