sounds about right.
Just remember - whatever you do, comparing 60G files will be slow...
Test this on a smaller chunks to see if you're getting the desired results first.

usync(8) System Manager's Manual usync(8)
NAME
usync - synchronize two setld inventory files to reflect current system status
SYNOPSIS
/usr/lbin/usync [-d] file1 file2
OPTIONS
Enables debugging. This will print the pairs of pathnames being synchronized on the standard output.
DESCRIPTION
The usync command is used to achieve inventory synchronization by merging two inventory files according to the pathname field of the inven-
tory records. The result is directed to standard output.
If the two inventory files contain records with the same pathname, the record in file2 is written and the record in file1 is ignored. If
either inventory file contains a pathname not present in the other file, the record containing that pathname is written to standard output.
To reflect the current system inventory, file2 should represent a later installation than file1.
RESTRICTIONS
The two inventory files must be sorted in ascending ASCII sequence on the pathname field.
ERRORS
usync: file is corrupt
Explanation:
Records in one of the inventory files are not sorted properly.
EXAMPLES
The following command produces a synchronized inventory for two versions of the OATDCB subset: /usr/lbin/usync OATDCB100.inv OATDCB120.inv
FILES
Subset inventory files
