Upgrading bitbucket 5.1 to 7.19

[TH IS]

Good day,

We are planning for the following scenario to upgrade our Bitbucket Server (currently installed on a Win 2012 R2) with external DB (MSSQL 2012).

We will start by cloning the current app server, create a new MSSQL server 2019 and backup -> restore the DB on the new SQL server

Run an in-place upgrade of the OS to 2019 on the app server and upgrade Bitbucket to 7.19

Pointing the app server to the new SQL server and start testing functionality, integrations, add-on apps and so on.

The current setup (5.1 and SQL 2012) will still be running in prod while testing is ongoing on the new setup.

The one question we have now is that once everything is verified on the new setup we will then stop the current prod setup, make a final backup -> restore of the DB, and a final delta sync of the application home directory from 5.1 to 7.19 and here where it's a little unclear whether the delta sync would actually work.

Found some info on this page regarding the content of the 'BUTBUCKET_HOME' directory: https://confluence.atlassian.com/bitbucketserver/set-the-home-directory-776640890.html and the part below 

where the Git repos and projects data are the most important thing. Is it only when no external DB is used this data is stored in this folder?

Is copy-pasting the content of the BUTBUCKET_HOME from 5.1 setup to 7.19 would suffice to make a fully synced app data?

Grateful for input and thanks in advance.
