Hello Shazia, The error is reporting that one of your items has no "dc.title" metadata field. DSpace requires that all items have a "dc.title" when they are imported. My only guess here is that it was somehow removed from your existing DSpace.
So, a few possible options: 1) Attempt to determine *which* item is missing the "dc.title". Add that "dc.title" field and re-export and re-import. This older thread describes how you can find the item which failed cause it was missing a "dc.title": http://dspace.2283337.n4.nabble.com/AIP-Restore-error-td4650376.html#a4652023 2) Another option is to just migrate your Database and Assetstore directory manually. You don't *have* to use the AIP tools to do a migration. Instead, you can just export your database, move it over. Then move over the config files & "assetstore" folder & reindex. This general process is described in this thread (the thread also describes upgrading the DSpace DB prior to the migration, but you can ignore that as long as you plan to stay on DSpace 3.2): http://dspace.2283337.n4.nabble.com/Problems-with-AIP-restore-td4673152.html#a4673166 - Tim On 5/28/2014 9:44 PM, Shaz UIC wrote: > Hello All, > > I am in the process of migrating the DSpace instance installed on a > Windows machine to Linux server.
