Migrating Bitbucket: Server Edition on Windows to Datacenter Edition on Linux Server

[Matthew]

Hello,

We are running Bitbucket Server Edition in Windows for several years, containing numerous projects, repositories and add-ons (plugin apps).  We procured Datacenter Edition licenses and will receive them soon.  We have (2) Red Hat Enterprise Servers ready for Bitbucket Datacenter (PROD & TEST).  Can anyone provide feedback on how to migrate this?  Any tips, do's or don't s would be appreciated :)

Thanks,

Matthew

Hi Matthew,

The general steps on migrating from Windows to Linux and moving from one server to another can be found in the following two Atlassian resources:

• Migrate Bitbucket Server from Windows to Linux
• Migrating Bitbucket Data Center to another server

We don't have specific recommendations for RHEL, though here are a couple things to pay attention to:

• Git version: RHEL repositories typically distribute Git 2.18.x. Depending on the Bitbucket version you are running on, you may need to manually install a compatible version of Git. Sometimes this means compiling it from source. 
• SELinux: we have seen some instances where SELinux seems to be more restrictive in RHEL systems in comparison to other distributions. Sometimes, this causes problems with Bitbucket when running it as a service. If the service doesn't start, remember to check SELinux audit logs as it might indicate why the process was denied.

Hope these pointers will set you off to a good start for the migration.
