Some suggestions:
- Your documentation did not mention this script. I did look. Seems easy to link it somewhere.
- I get that it's a business to run, but for accounts that were basically not being charged (less than $1 a month) to automatically move to a $50 tier is not the right way to handle it.
- I have migrated and downgraded now.
- Why not just allow legacy indexes (if they're still small enough) to stay in their region? Was it REALLY that expensive to have a few indexes in US-west-2 to warrant all of this?
