Make a backup of the signal-cli data before upgrading - as zetabeta already mentioned, it is in "~/.local/share/signal-cli/". See also Upgrades.
Another thing to note: Use Signal (including the signal-cli) on all your registered / linked devices from time to time. Devices may get unregistered / unlinked when they are not used for a long time (months? years?) - I have read several reports about that.
