Recently I was performing a test migration of a site from MOSS to SharePoint 2010, using the stsadm export & import options.
The site contents were with all the versions & no file compression:
stsadm -o export -url "
Then the site was imported into a blank SharePoint 2010 site:
stsadm -o import -url "
The import process failed with following error:
FatalError: The version of the package 12.0.10.0 is different from the current version this program supports, 14.0.0.0.
Debug: at Microsoft.SharePoint.Deployment.SPDeploymentSchemaVersion.Validate(SPSite site)
at Microsoft.SharePoint.Deployment.SPImport.Run()
Progress: Import did not complete.
The culprit is the line:
<SchemaVersion Version="12.0.10.0" Build="12.0.0.6514" DatabaseVersion="476278" SiteVersion="0" />
in SystemData.xml.
Replace Version="12.0.0.0" with Version="14.0.0.0"
and Build="12.0.0.6514" with Version="14.0.4762.1000".
Here the build number "12.0.0.6514" is the MOSS version of the servere where the backup was performed and "14.0.4762.1000" is the build number of the SharePoint 2010 server where the import is being performed. Check the versions on both the export & import servers and replace the above values with the ones on your servers.
I edited the SystemData.xml file and ran the stsadm import process after that and it completed smoothly. There were a few errors and warnings, however, but those did not abort the process. If there is another critical error resulting in the import operation being aborted, look at the import.log file (in th folder where the site contents are being imported from) and there will be afair indication of what went wrong. This is the reason I export contents with the nofilecompression option, as it gives me the ability to have a look at the contents and find/rectify the cause of the errors.
