Well, the utility is designed to do so.
However, as I have not yet migrated, have not tested corner conditions. You would get a better answer from somebody else who has used it.
I can forsee some problems in backfill. Vjay confirmed that NSE currently provides 1 day backfill or about 400 records. For MCX, I can see about 20 days or upto 30000 records. For GOLD I even saw 90000 records ! So timer settings will have to vary for backfill depending on exchange. Of course, you could use Nest Plus backfill that has a more consistent range.

backfill data [source Scrip {right click} - Intraday Chart-Data Table, 1min tf]
for NSE - 375 records
for MCX- 810 to 840 records
[both contains 1 min tf data] and better to take the data from Intraday Charts - Data Table . the data is pure and identical to the MW data rather than the Nest Plus data which in case of MCX i have found that it contains some zero data.
so u upgrade the timer for the backfill in case of Nest2Ami
