FWIW, I've seen through a lot of upgrades from 1.x to 2.x and metadata
issue's never been a part of it. You should be able to safely upgrade and
then to configure HA. Note that you cannot directly upgrade into HA mode
yet, you have to upgrade to a regular 1.x to 2.x, and then as a next step,
Rollbacks are supported as long as you haven't finalized the metadata
upgrade. I hope this covers the "backward capable" metadata question. If
not, please rephrase that point?
