can i upgrade alpha2 to alpha3?

Question

I already deploy alpha2 to some client,and i can update multichain software to alpha3.But params.dat of alpha3 should add some new item.

When i updated software and use api "create upgrade" to update 20003,how to change params.dat file.thanks

Answer 1

You don't update the params.dat file when updating the software. Instead you should do these steps:

1. Upgrade the software on each node
2. Upgrade the blockchain protocol (using create upgrade / approvefrom) to support the new features
3. If you want to change any of the blockchain parameters from their default values, upgrade those parameters using the same method as in step 2.
