protocol upgrade

+2 votes

I have some questions regarding using the Multichain software. We have downloaded the version 1.0.4 version of Multichain and have made a new chain. We are attempting to upgrade the protocol of this chain to 20002 from 10010 using the instructions written on https://www.multichain.com/developers/upgrading-nodes-chains/. During the upgrade process (after step 3 to be exact), an error pops up like below:

error code: -8

error message:

Invalid protocol version, cannot upgrade to future version

So we downloaded the 2.0 alpha 2 version of the software, and proceeded to run the same chain using the 2.0 alpha 2 version instead of the 1.0.4 version, only to be met with another error

ERROR: Parameter set for blockchain kaitest was generated by MultiChain running newer protocol version (10010) Please upgrade MultiChain

So, to summarize, how can we upgrade the protocol of our blockchain from 10010 to 20002 without encountering such errors above?

This happened because the upgrade schedules for the 1.0.x and 2.0 series are somewhat separate. Version 2.0 alpha 3, scheduled for release in the next days, includes support for all 1.0.x protocols released so far.
