I'm trying to import a site from one 2013 farm to another. I have all the .cmp files. when I run import-spweb in my 2013 farm, I always get an error that the "Cabinet file is corrupt."
Using FQDN/_vti_pvt/service.cnf I noticed that the site was exported from a farm with build 220.127.116.1163, mine is 18.104.22.16820.
I installed all the patches to get mine up to 4763, but it's still showing 4420. Not sure if this is my problem?
