Adding old records to PARTTRAN table, is it safe?

Recently we've sort of started again from scratch with Vantage, with a clean SQL 2005 database apart from parts + quotes + financial data and a few other things.

At the time we were not in the position to have the PARTTRAN table carried over, however, this is something we now realy need.

Now, the records in this table are just a running history of a parts transactions ?. If I copy the old data back into this table, altering progressrecid's so that they don't clash, I'm just adding back the history, nothing else will happen as no transactions themselves are being performed (e.g. effecting part costs).

Thanks.
