Currently I have MC on three nodes (testing stage) and I'd like upgrade them to MC version 2 (alpha). The following info:
"Existing chains running protocol 10008 or later can also be upgraded, using the create upgrade, listupgrades and approvefrom APIs." is useful, however, I wonder if there's any more specific writing on this subject to make the upgrade smooth. For instance, sample code for "create upgrade" would be a good start. Then, I couldn't find any man page for "listupgrades" from cli interactive mode nor "approvefrom", how do I access these two specific APIs?
And should I upgrade the seed node first or the other way around?
