 # odoo17-to-18-community-upgrade-docker
-this description of action I did to upgrade a odoo community v17 to v18
+July 28th 2025
+
+I couldn't find clear explanations and I don't have a devl odoo env.
+This is a description of the actions I did to upgrade a odoo community v17 to v18 with standard docker containers
+
+0) to avoid any module problem, remove the custom V17 installations:
+    in the odoo env, go to apps, look for all modules installed and remove the custom ones
+      you may find the list in your ./custom (the folder which links to /mnt/extra-addons in your docker-compose)
+
+1) upgrade your current env to last V17 version (see in V187 folder):
+    1) with provided latest V18 Dokerfile, entrypoint.sh and wait-for-psql.py, create new image, run existing V17 on a docker from that new image
+       see in V17 folder the build command and docker-compose.yml odoo.conf related
+       remember on which docker runs your pstgres (in my case postgres-20250725-mylucdatabase)
+       
+2) Create a Migration env based on V18 (see in V18-MIG folder): 
+    you need a dedicated Dockerfile based on latest provided odoo V18  (in my case 20250725)
+    a) update your V18 Dockerfile
+       - add vim, curl, git, unzip in the early installation
+       - create a directory for OpenUpgrade scripts (line 95)
+       - add the install of openupgradelib (line 96)
+       - add the reference to directory /var/lib/odoo/OpenUpgrade (line 98)
+    b) update your v18 entrypoint.sh
+       - you need to add the migration instruction
+    c) update you docker-compose.yml
+       - you need to run once only (no restart)
+       - you need to add reference to the local unzipped folder V18 OpenUpgrade
+    d) update your odoo.conf with references to the running postgresql
+      - you need to reference your V17 postgresql running docker and the db_name to migrate
+      - you need to add variables
+    e) download the OCA OpenUpgrade Scripts
+        - download and unzip or git clone the OpenUpgrade V18 env to the local folder (in my case ./OpenUpgrade/ )
+    e) run the migration:
+        - launch the docker (docker-compose up -d) 
+        - monitor the logs (tail -f ./logs/odoo.log)
+   
+4) Create a V18 env based on V18 (see in V18 folder):
+   - Based on latest Dokerfile, entrypoint.sh and wait-for-psql.py
+   - copy the filestore content to the new V18 env
+   - Create your docker image
+   - run the new v18 docker and monitor the logs (tail -f ./logs/odoo.log)
