Now that you have installed the new database package. You need to update your `database.json` configuration files located in `./config/environments/{env}/database.json`.
You can now only use the connector name instead of the complete package name.
**Before**
```json
{
"defaultConnection": "default",
"connections": {
"default": {
"connector": "strapi-hook-bookshelf",
"settings": {
//...
},
"options": {}
}
}
}
```
**After**
```json
{
"defaultConnection": "default",
"connections": {
"default": {
"connector": "bookshelf",
"settings": {
//...
},
"options": {
//...
}
}
}
}
```
## `ctx.state.user`
Previously the ctx.state.user was populated with the user informations, its role and permissions. To avoid perfromance issues the role is the only populated relation on the user by default.
## File model
The file model has been update. The `size` field is now a decimal number, allowing correct sorting behavior.
You will need to clear some database indexes if you are using either Mysql or PostgreSQL.
:::: tabs
::: tab Mysql
Run the following statement in your database:
`DROP INDEX SEARCH_UPLOAD_FILE ON upload_file;`
:::
::: tab PostgreSQL
Run the following statement in your database:
`DROP INDEX search_upload_file_size;`

## Groups become Components
If you were using the groups feature you will need to apply some changes:
Start by renaming the `./groups` folder to `./components` in your project root folder.
