aaPanel will have a few features less than it. If you only use its free features, the functionality is basically the same.
In addition, if the panel used by your current server is 6.x, in theory, you can use install command overwrite install the panel to directly switch to install aapanel to complete the switch. Of course, for your data security, please backup the data in advance and operate at the least amount of users.
