If the view update\replace is not required, then while importing the report, select the appropriate view, and replace the report.
Before deleting the other view, make sure it doesn't have any associated reports.
I suggest, take a backup of both systems for the report\view in question, and then go ahead.
What version are the screen shots from? I am trying to locate reports with sub queries for troubleshooting an issue and they don't seem to appear in the Reports tab on my Views. I found 3 sub queries on one Incident Management View, but I know that I have several using Change Management that are not appearing.
This was version 9.1.03. This has been awhile but I ended up backing everything up just to be safe. I believe I did a search on the xml files to find the "Append 1" then determined from there what to do with it.
