Apply Upgrade Solution Issue

Hi Everyone,

I have imported a solution into my Prod instance by using "Apply Solution Upgrade" option to delete one field, but while trying to upgrade solution I realized that the system is trying to delete some other components which are required. Don't know why it is trying to delete the other components but those are required, may be some one removed (not deleted) those components from the solutions in Dev. Now I want to abort the solution upgrade process but I have 2 solutions in my Prod instance. My question is can I delete the "_Upgrade" solution from my Prod instance? Will it cause any issues?

Thanks,

Phani.
