@dislbenn can we remove the hold label?

I've reached out to the CICD team to discuss merging into ACM 2.7.8 and it seems like it's not quite ready yet. I expect that it will be open hopefully by tomorrow or sometime this week, so this PR will need to be held until then.

FYI @sahare. I will merge this PR as soon as ACM 2.7.8 is open!

@dislbenn Please do not merge this PR until we have more information about issues caused by OADP upgrade, Thanks!

@dislbenn We can remove the hold label now and the PR is good to be merged, Thanks!
