C.1.1 Stopping the Old Product (V1.0.x)

Use the following procedure to stop the virtual appliance of the old product.

Make sure that the shared folder of the old product is not accessed. If it is being accessed, wait until the access is completed or stop the operation that is accessing it.
In the Used cache capacity panel of CSG Web GUI, check that "Untransferred data" is "No". If "Yes", wait until it changes to "No". You can estimate the completion time of the data transfer as follows:
1. Calculate the average cloud transfer performance (MB/s) from the performance data in the Cloud transfer performance panel of CSG Web GUI.
2. View the "Untransferred" value (GB) in the Used cache capacity panel of CSG Web GUI.
3. Estimate the transfer completion time using the values obtained above in a and b.
  Estimated transfer completion time (s) = ("amount of untransferred data" + 1) x 1024/"average cloud transfer performance"
Log in to the console of the old product using the Administrator account (administrator).
Execute the following command to stop the old product.
```
# csgadm power stop
```

Note

Do not launch the old product while you perform the procedures described in the later sections from "Connecting the Virtual Disks of the Old Product" to "Performing a System Migration". If you launch it accidentally, there may be inconsistent data between the cache and bucket. In this case, you will need to start the upgrade procedure from the beginning.
