my immediate reactions are:
1. where are these dupes coming from?
2. finding / correcting dupe rows should be generalizable, if you could
show more specifics

I doubt this exists, but I figure it is worth asking...
We recently had some schema changes, and while the schema migration ran
fine we have a lot of record migrations to do.
We have a scenario like this:
Object A now has duplicates
Object A must be de-deduplicated, preferring the earliest occurrence
The relations of duplicates must be transitioned to Object A, if
they do not already exist.
Typically the solution is for me to write a long, custom migration
script. I really hate doing that and am wondering if there have been
any ancillary projects in this area.
