CommServe Hardware refresh from Windows 2012 & SQL Server 2012 to Windows 2022

Hello,  We plan to perform a CommServe hardware refresh from Windows Server 2012 to Windows Server 2019. Commserve is on Feature Release 28, and the SQL server version is 2012. What is the upgrade path for the Commserve with SQL running in 2012? Do we need to first upgrade the SQL to 2014/2016 and then perform the Hardware refresh? Or is it possible to perform a hardware refresh without upgrading the SQL? The documentation doesn’t mention about SQL upgrade path.  CommServe Upgrade with Hardware Refresh: Overview (commvault.com)

Disk retention while using Auxiliary copy

Hi Team,We are configuring Storage policies and including Tape for auxiliary.Please find the below requirement. Requirement 1: First storage policy will configure Hourly, Daily, Weekly, Monthly and Yearly schedule for disk and then only Weekly, monthly & Yearly will go to auxiliary copy of tape.Requirement 2: Second storage policy will configure Monthly (keep disk) and that is no need for auxiliary copy.Our Clarifications:Is it will configure separate schedules for Weekly, monthly & Yearly? After retention of backup, the data will delete from disk without auxiliary copy (requirement2).Please advise.

Exchange Online Backup with MS Archive

Hi All, i have an short question regarding the exchange online mailbox backup.  The companay decided to activate the Micorostf Archive feature for Mails.  https://learn.microsoft.com/en-us/exchange/policy-and-compliance/in-place-archiving/manage-archives?view=exchserver-2019&viewFallbackFrom=exchonline-ww So every mails wich are older than 180days should be moved to the archive.  Is there any impact to our Backup ? My opionion is not because we are running every 4 hours an backup and when a new mail is dected the mail would be backuped directly and is saved on the backup storage, When now the Micorosft archive policy is moveing the mail it doesnt belong to commvault. The Backups are incr 4 ever so no impact.  is that correct ?

Change/remove SQL Impersonate Users via API or PowerShell modules

Friends, I try to find a way to automate the sql61props via Rest API or Powershell modules. Does anyone has experience with this? My goal is to remove the MSSQL Credentials (Impersonate Users) or replace by dummy and to disable overrideHigherLevelSettings per Client as this is now managed at Server Group. I tried to use Get-CVClient, update $_.pseudoClientInfo.idaInfo.sql61Prop as how I want to have it and post this via Set-CVClient. The answer is that it is successful, but nothing is changed. I also tried to update the settings directly via Submit-CVRESTRequest with the result; answer like succesful, but nothing done. I was looking at sending an XML to send the update, but I can’t find the parameters. Can anyone help me with this?Thanks in advance,Maurice

Delete empty DDB

Hi All, maybe you can help us.  During an human error the option: DDB horizontal scaling threshold number of subclients per DDB 1  was set to 1. This cause last night  DDB [xyz] crossed number of subclients threshold hence created a new DDB [xyz] for adding new Subclients.  Now we have 2 DDBs   So what happen is that all new subclients will be run against the ID:44 and all old one deduplicated against ID:41  This happend also for another engine.  The new created id is actually empty. Sealing did not help. also we tried: qoperation agedata -delbystoreid -sid 44 ft Q_DATA_LOG Actually running support case does also have no idear if and how can this ddb can be deleted.  The problem is that we dont have enoug space in metallic cloud for running in baseline. thanks for your help
