Hi, i've spend some time searching the way to export huge library from 2010 server and import it to 2013 server but have not found complete and free solution, so here is the way :
First use granular backup at source server, select whatever you want so we get cmp file or many cmp files ( depending on library/list/site size ). Then open it like cab, extract contents. If you got lot of files then extract them all and place all contents
to one folder. Edit file SystemData.xml and change version number from 14 to 15 like this : <SchemaVersion Version="188.8.131.52" Build="15.0.6120.5006"
Save, pack all contents back to cab.
If multiply cabs was extracted pack them to one file anyway, no other changes needed ( so you will got one big cab))
Well, my only goal was to move (2010->2013) huge doc library with cross-site lookup to another list and it worked, even cross-site links worked just fine. I have not found any other way to solve this task.
