Change Repository for Backup Copy job without full backup

[hslee2]

Hello,

I have a question about changing our Veeam environment.

Here's a summary of our environment:
- We have sites A and B, each configured with local backups via NAS storage.
- Backup copies are configured as iSCSI-type Refs filesystems between sites.
- Site A has agents and unstructured data, while site B has agents and a Nutanix environment.
- Our goal is to convert all storage to immutable storage, while maintaining a backup chain between both sites. (Due to network usage restrictions.)
- Agent Jobs are configured with a 1:1 policy and source server, and Backup Copy is 1:N.

- The version is 12.3.2, and each Backup Copy repository has the Per-machine option enabled (the folders are actually separate).

Here's a brief summary of my plan:
- I'll link a new Linux repository to VBR and manually copy data (rsync). - After copying is complete, I use Repository Rescan -> Agent Job to change the repository and perform a map backup.
- For Backup Copies copied during the same period, I plan to split the 1:N copies and configure the source objects individually or in small groups.

There are some key considerations here:
- Will an incremental backup, rather than a full backup, be performed after the change?
- Can Nutanix Backup Copies change the repository in the same way?

I'd like to hear about everyone's experiences.
Thank you in advance for your advice.
