Run Axon, then once you have its blockchain up to date give it your saved backujp AXIOM wallets.

(Stop the daemon, copy a wallet into data directory, fire up coin again, checkwallet, recover wallet if need be, send the coins to an address created in the new empty wallet you got when you inititlly started AXON if you have several AXIOM wallets to process and consolidate or just want to start clean without umpteen megabytes of wallet left from years of staking.

Basically all your saved AXIOM wallet backups also act as old saved AXON wallets, all coins prior to the point where the chains diverged should survive.
