 ### Upgrade SeaDoc from 0.8 to 1.0 for Seafile v12.0
 
-If you have deployed SeaDoc extension in version 11.0, please use the following steps to upgrade it to version 1.0.
+If you have deployed SeaDoc v0.8 with Seafile v11.0, you can upgrade it to 1.0 use the following two steps:
 
-SeaDoc 1.0 is for working with Seafile 12.0. SeaDoc and Seafile are deployed in the same directory. SeaDoc has no state in itself. You can simplify delete old configuration file and directory of v0.8. Then deploy SeaDoc 1.0 as following.
+1. Delete sdoc_db.
+2. Remove SeaDoc configs in seafile.nginx.conf file.
+3. Re-deploy SeaDoc server. In other words, delete the old SeaDoc deployment and deploy a new SeaDoc server on a separate machine.
 
-In version 1.0, we use .env file to configure SeaDoc docker image, instead of modifying the docker-compose.yml file directly.
+Note, deploying SeaDoc and **Seafile binary package** on the same server is no longer supported. If you really want to deploying SeaDoc and Seafile server on the same machine, you should deploy Seafile server with Docker.
 
-Download [seadoc.yml](../docker/ce/seadoc.yml) to the Seafile `seafile-server.yml` directory, then modify Seafile .env file.
+#### Delete sdoc_db
 
-For community edition:
+From version 1.0, SeaDoc is using seahub_db database to store its operation logs and no longer need an extra database sdoc_db. The database tables in seahub_db are created automatically when you upgrade Seafile server from v11.0 to v12.0. You can simply delete sdoc_db.
