Hi Christopher,
we have followed the same document and we have built a New AVA-C8 AMI with the version of 4.2.2 AVA-c8 with the attatching of AWS s3.
The backup application we are using currently Veritas Netbackup. We have mounted our new AVA-c8(SACNPAWS008) to Same media server and created one more Storage unit to New one also. Initiated the backup to new appliance SACNPAWS008.
Please find the below mounted details.

- Currently in the production 3.2v AVA-c8(SACNPAWS002) and all the data is available in that.
- We seen the procedure like detatching the EBS volumes and need to attatch it to new AMI SACNPAWS008 with the configuration file.
Questions:
1. While attatching the EBS volumes any data or volumes will lost any thing? In SACNPAWS002 cloud data presents shows "Estimated Cloud Space is : 39 TB"
2. The same S3 bucket connected our new AVA-c8. Here Cloud Data its Shows "Estimated Cloud Space is : 25gb ( 40Tb empty space )". When attatching cloud data where will go ?
3. If possible please contact us through call or mail to success this upgradation with out any data loses.?
We will have Web-ex session to complete this activity,
