Sometime last year my party wanted to try V10.
Party gave it a test run!
We ended session at a snowy location, party’s tokens were on the board ready for battle.
Party didn’t like v10 so we Reverted to v9
It’s been nearly a year, so we attempted to migrate to V11 (with a clone of my current world)
Everything went smoothly until I logged in.
It was the same snowy location, ready for battle.
Almost like everything from my old V10 save file was brought forward.
I’m not super savvy with this kind of stuff… could someone help me?
TLDR
Tried migrating v9 → v10. Reverted v10 → v9.
Year later tried v9 → v11. Game reverted all progress to the old v10 save.

Between v10 and v11 the databases in Foundry changed. What I’ve encountered most often in other cases where users mentioned this exact issue is that the world was migrated to v11 (you mention that it was migrated to v10 and back to v9, but it’s possible that you briefly ran it in v11 and reverted back to v9 somewhere after v11 came out).
If the v11 databases exist, the new v9 and v10 data won’t get migrated to v11 when you move over. There’s an easy way to fix that, though.
Before you migrated from v9 to v11, you’ll have made an export of the world. First off, make a copy of that export so you have a safe copy.
Then, if you unzip and check inside of that export, you’ll see a data folder.
Check inside of the data folder, and you’ll likely see something similar to the image below.
To re-migrate the new v9/v10 data to v11, and get rid of the old v11 data, delete the database folders and keep the .db files.
Then, re-import the world to Forge with the Import Wizard.
When you run that world on v11, it’ll re-migrate the new v9/v10 data to v11 format, and allow you to pick up where you left off most recently.
Let me know if you have any issues, and I hope this helps!
Hello Thanks for the solution , I was Wondering if it work to V10-patch 8 ( build 312 ) to the V12 stable 7 ( build 331)
I tried to migrate a clone world to my main world for testing.
and I found myself on an earlier version of the world, most of the modifications, characters, skills etc. that I added over the last 8 months have disappeared, just like the players who recently joined the game.
If v11 database files already existed from 8 months ago (i.e. the world was opened in v11) then those old database files will need to be cleared first so that the pre-v11 .db files will be converted into new and current v11 db files.
Keep a backup of your v10 world somewhere safe and test the steps shown there with an export of a clone of your world.
after a first try the results are the same, I remain on a game which has not taken into account the latest modifications made
I imported a copy of my main world by deleting the database folders and keeping the .db files. as explained, once the import was done I was able to restart the game, shouldn’t it offer to update my world ? since the copy is in v10 ?
When you run your world on v10, does it have your latest changes?
If so, then the process above should work. If it doesn’t, then we will need to work with the world that does. If it does, but the process above doesn’t work, then something else might be at play.
It’s a little tricky to tell what exactly is going on without seeing the world myself.
If you can confirm that the world export has the content you want on v10, please PM me a copy of the world or create a private ticket in our #ticket-support channel on Discord and share the world there.
