I have used export-spweb and import-spweb to move multiple sites around in SP2010.
After import-spweb I notice that some libraries are really messed up. When I try to add an item to the announcements list I see 3, yes 3 save buttons! It seems that some guids somewhere mustn't be getting update and goodness knows how many inconsistencies there are across all the OOTB lists.
Is there a known issue around using import-spweb? More importantly is there any easy way I can diagnose/fix this issue?
