Hi using transparent proxy, and for example does upgrades plugin support upgrading to new implementation which is already deployed and address is known. I do not know if upgrades.prepareUpgrades is for this use-case? So basically I would like to have implementation deployed and after sometime, point proxy to new implementation.
Do I do prepareUpgrades and deploy with it implementation contract, this would validate it that all is ok (storage layout etc), but actual upgrade is done with executing ProxyAdmin.upgradeAndCall manually (without upgrades plugins) ?
Cause clearly I cannot do it with upgradeProxy as here implementation is deployed with proxy in same action.
Thanks.
