We are planning on doing an upgrade from 5.6.2 to 5.7. How long does the upgrade take? I know the 5.3.3 to 5.6.2 took about 2-3 hours for us since it had to do the database upgrade. Is there anything in 5.7 that can take a while? Also, have the steps for upgrading stayed the same? Ex) Run the upgrade setup and click next a bunch of times... ?
