Hi,
When making an inplace upgrade of an Windows server from for ex. 2012R2 to 2022. Does Commvault see that as a new server when calculating the Capacity Licenses in use for Commvault Backup and Recovery?
Commvault Capacity Licens Calculation - Commvault Backup and Recovery

Hello
No, upgrading the OS does not consume an extra license and it does not affect Capacity License. Capacity is calculated based on the last Full backup of each subclient.
Capacity-Based Total License Usage - https://documentation.commvault.com/2023e/essential/capacity_based_total_license_usage.html
In capacity-based total license usage, usage is calculated by taking the largest data protection job for a client during the time period (one month), regardless of whether the client is still actively used at the end on of the billing period. This means that out of all jobs for a given client, the software uses the largest full backup job or synthetic full backup job for that month as the total. The size of the largest job is used to reflect the usage for that client for the entire month, even if the client is removed before the end of the month. The sum of all of the largest jobs for all unique clients is the total usage billed.
Thank you,
Collin
