spec to upload

It depends on what you need to achieve.
If you need to update your old spec elements (SPCO references) or add new SPCO,
then you may update old spec using specon format.

If other office will send you totally new spec,
then I believe renaming of old spec and creation of new one and replacing of references will be solution...

But as I said, it depends  on the situation.
