As of the Kava 10 release, all upgrades are done as in-place software upgrades. The chain id no longer updates and the block height is never reset to 0, as was the case with all upgrades prior to Kava 10. Historical data for all upgrades since Kava 10 are available on the mainnet data node endpoints. Some data may need to be queried with the historic verison of the Kava CLI.
Note that the Kava 5 upgrade was reverted. Those data are also available: API & RPC
