How can i update miranda myself correctly

Hi,

i wonder how i can update the portable version of miranda myself, correctly.
Because in the last weeks most the time there was a new portable miranda version available and a few days later a new version released on the official site so that the portable version was out of date again.

Is it enough to just copy the unpacked official miranda application data in the apps folder on the portable version and overwrite the old files ?

best regards
