Created attachment 1449130 [details] issue_found.gif Hi, +1 for validation errors on imports; checked with, 1. if .csv is blank 2. if header is diff than `Name` and `Provider` 3. if we got 2+ arguments In VM Table, checked following - 1. if vm exists in diff migration plan 2. if empty name specified 3. if vm available However found, when vm already exists/used in another plan, it won't give any validation error in tooltip which looks odd and confusing, we need to correct that. (checked attached gif, wait for last part) Verifying this since it is RFE, raising another bug for issue found. Verified on: 5.9.3.1.20180606184006_8d120c0 Thanks!
