Migrating Revenue Recognition Schedules?

We're doing a data migration, NetSuite to NetSuite (moving to OneWorld).  We've done this before, but this is our first time trying to migrate revenue recognition schedules data.  The schedules themselves can't be migrated (they're system generated), and we're looking at two options:

1) Migrate most transaction data as is, i.e. posting it to the same period in the target system as it was in the source. Filter out (i.e don't migrate) journal entries created from rev rec schedules. Manually re-create those journals in the target systems, using the "Create Rev Rec Journals" task.

2) Migrate all historical data to a dummy period, without rev rec (remove the templates from the item records).  We lose some historical financials, but we can still report on sales, purchases, etc.  Migrate current data as in (1).
