Orion NPM Backup keeps failing

Hi,

Currently trying to backup my  orion database , so that I can migrate it to a new server. The SolarWinds NPM will stay on the orginal server.  I used the SolarWinds Technical Reference -  Moving Your Orion NPM Database document.  I moving from SQL 2005 to SQL Server 2015.

It  looks like the database size is 79gb. It been running fo over 4 hours I get the below that it failed. I stopped the services as stated in the document.

Any advice would be useful on what to do  ?

Thanks
