i upgraded a sharepoint 2007 project to 2010 using database attach approach. all the customizations are working apart from custom list created through list definitions.
when i export 2007 list to a cab file and updated the systemdata.xml file to new schema re import back to 2010 it started working only that list
old
SchemaVersion Version="12.0.0.0" Build="12.0.10.0000" DatabaseVersion="44098" SiteVersion="0"
new
SchemaVersion Version="14.0.0.0" Build="14.0.4762.1000" DatabaseVersion="44098" SiteVersion="0"
i cant do this for all the list since site got hundreds of lists. how can i solve this issue
