Bitbucket Data Center Mirror OS Migration – Reusing Existing Data & Performance Impact

[Pardhusri Satish Babu Obulasetti]

We are currently running Bitbucket Data Center version 7.21.4 hosted on AWS with Ubuntu 20.04 (Focal). Our configured Mirror servers are on version 7.21.18, deployed on vSphere VMs with Ubuntu 22.04 (Jammy).

We are planning to upgrade the Mirror OS from Ubuntu 22.04 (Jammy) to Ubuntu 24.04 (Noble).

Before proceeding, we have a couple of questions:

1. Can we reuse the existing data from the current Mirror VMs during this OS migration to reduce initial sync time and associated costs?
2. Are there any known performance implications or compatibility concerns when migrating Mirror servers to Ubuntu 24.04 (Noble) while keeping the Bitbucket version unchanged?

Any guidance, best practices, or documentation references would be greatly appreciated.

Thank you!
