If you are not using any other devices connected to the RPi2, I would set up the RPi4 with a fresh install on a new SD card (use the newly released 64-bit OS). Get WeeWX installed, copy over all your customized files (weewx.conf, skin.conf, any custom drivers or services, etc), install any extensions you're using. Get the new RPi4 running correctly before you ever stop WeeWX on the old RPi2. When you're happy the new Pi is running the same as the old one, stop WeeWX on both Pis and copy the database from the old one to the new one. Then start WeeWX back up on both, and make sure the new one has the archive and is running well.
But if your old RPi2 is working and is just running WeeWX, I don't know if there's much reason to upgrade to a RPi4.
