Building the index will take some time. Purging data from the index as you purge the actual data will also take extra time. The more indexing there is, the longer it takes to completely file or delete a record.
Purge the data first, then build your index with nothing but clean data.

We are trying to do some system cleanups. We found that our PO file has over 10 million records dating back some 7 years. We've decided that 2 years of PO history is plenty to keep on file. Currently there are no indices on this file. Our question is would it be quicker to do a select and delete of the older records before building an index on invoice date or would it be quicker to build the index first to use in the select for the purge? This index has been identified as being needed for some reporting. My thinking is that while the select for the purge may go quicker, if the index is in place prior to the purge then the delete process not only has to delete the selected records it also has to update the index on the fly.
