When I was restore the SharePoint site backup file from one SharePoint farm environment to another SharePoint farm and got the following error message “Restore-Spsite: <nativehr>0x8007003</nativehr><nativestack></nativestack>”
Cause:
1. It might be SharePoint version not unique between source and destination.
2. Backup file may be corrupted or backup not happened properly
Resolution:
For my case, SharePoint version not unique between source and destination SharePoint Farm, So I have install appropriate SharePoint patches in the destination server to keep the unique versions and was able to restored the site successfully.
