I've encountered Search issue after content migration from SharePoint 2007 to SharePoint 2010 by Content Database approach.
actions performed before migration:
run stsadm -o preupgradecheck (no issue)
run Test-SPContentDatabase (no missing features)
deployed custom files (.ascx, .aspx and dlls)
After all the content has been migrated to SharePoint 2010, generally no obvious issue and tested pages can be open.
Then I perform full crawl in CA and it was successful, from crawl log able to see there is plenty of pages has been crawled.
However, when I try to perform search, I hit error which no further description except a correlation ID, which no useful information after check in SharePoint log.
My question is, how can I perform troubleshooting to solve the issue above?
Please help, thank you in advanced.
