#### MME Diameter Error using v2.2.x
|
||||
|
||||
If you see the Attach reject [EMM_CAUSE:15] with Diameter Error [Result-Code:3002], it means that you may use the old format DB schema.

At this time, you need to check the DB schema is in the form below by using the command the below.

```

If you see below, you are using the old format DB schema. Therefore, MME sends Attach Reject [EMM_CAUSE:15] with Diameter Error [Result-Code: 3002] and it does not work properly.
|
||||
|
||||
```
|
||||

|

|

If you are using old format DB schema, please perform the following step.
|
||||
|
||||
1. WebUI logout
|
||||
2. Install new WebUI with the following command.
|
||||
```
|
||||
$ curl -fsSL https://open5gs.org/open5gs/assets/webui/install | sudo -E bash -
|
||||
```
|
||||
|
||||
3. Log in to the new WebUI and add new subscriber information.
|
||||
4. Make sure it is a new DB schema as below:
|
||||
```
|
||||
$ mongo
|
||||
> use open5gs
|
||||
> db.subscribers.find().pretty()
|
||||
{
|
||||
...
|
||||
"slice" : [
|
||||
{
|
||||
"sst" : 1,
|
||||
"default_indicator" : true,
|
||||
"_id" : ObjectId("60969fe7de8743b3c7b1a973"),
|
||||
"session" : [
|
||||
...
|
||||
}
|
||||
```
|
||||
|
||||

If the following MME log occurs while connecting to the UE, it means that the Open5GS upgrade was not properly performed.
