15.4. Migrating an Application to Another Gear

There may be cases when an application must be migrated to another gear.

Procedure 15.1. To Migrate an Application to Another Gear:

Create a snapshot of an existing application:
```
$ rhc snapshot save App_Name
```
Verify that the App_Name.tar.gz file has been created in the working directory. After confirming the application snapshot is saved, delete the existing application:
```
$ rhc app delete App_Name
```
Create a new application using the same cartridges, but with the correct gear size:
```
$ rhc app create App_Name Cart_Name -g gear_size
```
Finally, restore the previously saved application snapshot to the newly created application. Be sure to specify the correct path to the saved application snapshot:
```
$ rhc snapshot restore App_Name -f App_Name.tar.gz
```
