upgrade bitbucket

[Irshad Ali]

Hello,

Currently I have Atlassian Bitbucket v4.5.2 installed on my Linux server and I want to upgrade to Bitbucket Data Center and Server 7.17 (Long Term Support release).

Is there is direct path to upgrade from my existing version to desired one? 

what is upgrade matrix?

The upgrade to 7.0 is a major set of changes and one that it is not advisable to skip over lightly.  I would recommend taking your 4.5 up to 5.16, then 6.10, then 7.0, then up to 7.17.

I would also quickly try 4.5 straight to 6.10, which usually won't cause you problems, but test it and see.  But the 6.10 to 7.0 step exposes you to significant change and risk, which you can minimise by taking the smallest step possible!
