using an old database as source for new inventree installation

[lobra07]

hello all

my pc once crashed and i had to reinstall windows
i didn't have any backup of my inventree
i have the data directory of the inventree old installation

my deployment was docker
any idea on how to use my old data with new installation of docker

thanks in advance

You may be able to follow the data migration guide

However if your old installation is not up and running this will be tricky.

If you have the "data" directory I would suggest the following:

1. Setup a new docker installation - https://docs.inventree.org/en/stable/start/docker_install/
2. Ensure all containers are stopped - docker compose down
3. Copy your old data directory and overwrite the new data directory (copy, don't just move)
4. Run docker compose --rm inventree-server invoke update
5. Fingers crossed...

Please post the output of that here. And make sure you keep an un-corrupted copy of your original data dir

thank you for the fast response

i did try it in different way

first Setup a new docker installation
then containers are stopped - docker compose down

then set env variables to the same as they were in the old setup

INVENTREE_DB_ENGINE=postgresql
INVENTREE_DB_NAME=inventree_old_db
INVENTREE_DB_HOST=inventree-db
INVENTREE_DB_PORT=5432
INVENTREE_DB_USER=database_old_user
INVENTREE_DB_PASSWORD=database_old_user_password

then i copied the PGDB file and MEDIA file into the new installation
then Docker compose up -d

and everything worked perfectly all data are back

thanks
