Delete a policy already created without affect the current backups

Hi Dell Avamar Experts,

I am new on avamar and here is my situation: 

The Policy "POL VM Daily WebApps" ran 1 month ago with 16 members without issue.   Today I saw all backups with this error:

log#1: 2023-03-21 00:11:55 avtar Error <41439>: Using invalid token:5ba93c9db0cff93f52b521d7420e43f6eda2784f
log#1: 2023-03-21 00:11:55 avtar Error <10542>: Data Domain server "ABC" open failed DDR result code: 4904, desc: Invalid API argument.
log#1: 2023-03-21 00:11:55 avtar Error <10509>: Problem logging into the DDR server:'', only GSAN communication was enabled.
log#1: 2023-03-21 00:11:55 avtar FATAL <17964>: Backup is incomplete because file "/ddr_files.xml" is missing
log#1: 2023-03-21 00:11:55 avtar FATAL <8941>: Fatal server connection problem, aborting initialization. Verify correct server address and login credentials.

The only change that I did yesterday was modifying the name of the Policy ...  ups!  fatal error!

I tried to leave the previous name.. but other error occurred while updating policy:

Code: 22540  

Category: application

Software source: MCS:BS

Severity: process

Summary: Invalid name character or name is too long

Error Message: Update group failed

So... I would like to know if these actions will be ok without affect the current backups, these is the plan:

1. Disable the policy involved to avoid run today again according to the schedule.

2. Create a new Policy with a name without symbols. 

3. Move the VMs whose had backup failed to a new policy and run the policy.

4. Delete the policy disabled 

What do you think?  any suggestions?
