Assuming you can get this setup, have you tested some subset of your
data on 9.6.9?:
1) Going from 8.4 --> 9.6 is jumping 7 major versions of Postgres. Do
you know that the data/code will work in 9.6.9?
2) Does the transfer have time built in for fixing problems on the 9.6.9
end?
3) If the answer 2) is no, then is there a plan to deal with changes in
the 8.4 database while working on the 9.6.9 database?
