I will test this on my full node shortly. Also, here is a WIP gist I have of the full upgrade instructions.

[alexanderbez]

Good work @fedekunze! Left some comments. Will test on my full node shortly.

addressed comments

[cwgoes]

According to @rigelrozanski this needs to set a high constant fee for the new crisis module's invariant check transaction.

[alexanderbez]

Yes, this needs the invariant fee param (from what @cwgoes suggested).

[fedekunze]

According to @rigelrozanski this needs to set a high constant fee for the new crisis module's invariant check transaction.

What's the value for it ?

[rigelrozanski]

$5000 USD was suggested by jae online

[fedekunze]

updated, please test again

[gamarin2]

I think it'd be great to add the procedure in /docs/cosmos-hub, something like upgrade-procedure.md

[alessio]

@fedekunze could we just rename this to scripts/export/v0_33_0.py?

[alexanderbez]

@gamarin2 I have a personal gist that I can port to here.

[cwgoes]

There's a typo I think - need to be careful since if we don't overwrite the old field it will remain (and the new field with the wrong name will be ignored).

good catch, updated

[cwgoes]

ACK - we should test this again with the exact exported genesis from mainnet once we have it.

[alexanderbez]

Tested an export on my mainnet full node w/o any hiccups.
