Transfer accounts - pkgacct problem

Well, I have 2 servers. Both with the WHM 11.44.1 (build 18) version When I tried to transfer an account, the process stop in this point: Archive/Tar/Builder.pm did not return a true value at /usr/local/cpanel/scripts/pkgacct line 90. BEGIN failed--compilation aborted at /usr/local/cpanel/scripts/pkgacct line 90. I tried to run on source server the command /scripts/pkgacct myusernameaccount Out the same error occurs I tried even a "/scripts/upcp --force" but system crashes at some point and never finish. There's something I missing? There's a way to workaround this to easily transfer the accounts from the "sick" server to the new one? Thanks
