Hi ​@Gianluca Rossi 

Kindly review the MongoDB version from the installation directory provided below and verify the details in the Details tab.

<commvault_installation_directory>\MongoDB\Server\bin

If in case the upgrade of mongo DB was skipped during the install process we can upgrade it manually 

Manually upgrade KB - https://kb.commvault.com/article/54441 

Hi Pradeep,

the MongoDB version have been extracted from:

<commvault_installation_directory>\MongoDB\Server\Latest\bin

c:\Program Files\Commvault\ContentStore\MONGODB\Server\Latest\bin>mongod.exe --version
db version v6.0.14
Build Info: {
    "version": "6.0.14",
    "gitVersion": "25225db95574916fecab3af75b184409f8713aef",
    "modules": o],
    "allocator": "tcmalloc",
    "environment": {
        "distmod": "windows",
        "distarch": "x86_64",
        "target_arch": "x86_64"
    }
}

So it seems that somehow, during the upgrade from 11.32 to 11.36 MongoDB was skipped.

Is there a way to upgrade to MongoDB 7.0.x ? Is it safe or can be distruptive ?

The kb you linked is for minor upgrade

Do we lose performance if we stay with this version of MongoDB ?

In the CVMongoInstall.log I’ve found the following entries (related to the CV upgrade to 11.36)

18188 1     12/23 10:39:41 ### ### IsVersionUpgradeRequiredPreInstall - Installed mongo version:6.0.1 LATEST_MONGODB_VER 6.0
18188 1     12/23 10:39:41 ### ### setRegistryValue - Set registry value: section Database, keyName sMongoVersion value 6.0.1
18188 1     12/23 10:39:41 ### ### IsVersionUpgradeRequiredPreInstall - Upgrade is not required as versions match

So there was no error at all, the installation procedure was looking for a 6.0.x version and not a 7.0.x.

Is it correct ?

Regards
