#### IMPORTANT Using v2.2.x

- **DB Schema Changes:** If you are using an existing subscription DB, you should delete the existing DB. Then you can add a new subscription DB.
{: .blue}
```
$ mongo
> use open5gs
switched to db open5gs
> db.subscribers.drop()
true
```

- **The New WebUI:** You have to log out using the old WebUI backend/frontend. Then, you can log back in again using the new WebUI backend/frontend.
{: .blue}
```
$ git checkout v2.1.7
$ cd webui
$ rm -Rf ./node_modules
$ npm ci --no-optional
$ npm run dev

## You should log out

$ git checkout main
$ cd webui
$ rm -Rf ./node_modules
$ npm ci --no-optional
$ npm run dev

## You can log back in
```

- freeDiameter version has changed from 1.3.2 to 1.5.0. If you want to compile the source code, you need to update meson subprojects as shown below.
{: .blue}

```
$ cd open5gs
$ git pull
$ meson subprojects update
$ cd build
$ ninja
```

Or just use a clean github repository.

```
$ rm -Rf open5gs
$ git clone https://github.com/open5gs/open5gs
$ cd open5gs
$ meson build --prefix=`pwd`/install
$ cd build
$ ninja
```
