Hi there,
We want to upgrade from confluence v5.10 to 6.15. We are using MS SQL server 2014. I was following the upgrade instruction and I am stuck at backup database step for following 2 reasons:
- We don't have login for SQL server management studio, we are using Windows Authentication - I am in Administrators group - have admin rights.
- I thought of performing backup by copying mdf and ldf files - but ldf file size is massive - 600GB. We don't care about the log transactions - to shrink the ldf file I have to connect to dB instance first which we are not able to.

Could you please help me, how to backup in this situation?
Kind Regards
Harkirat
