Disk Space Needed for 10.20.1

[mikesmithwsu]

I'm about to upgrade from 10.14.0 to 10.20.1, and looking at the release notes, it says I need 150 GB of space. The release notes for upgrading to 10.14.0 said it only needed 400 MB of space. My main drive running the OS has 37 GB free.

Does anyone know where this 150 GB of space is needed? For Tomcat? or MySQL?

Thanks!

@mikesmithwsu Hopefully you aren't running the JSS Tomcat app on the same system as your MySQL database. If you are, you might want to plan on changing that sooner rather than later. For an upgrade the biggest consumer of space is going to be the MySQL database changes during the upgrade. As a rule of thumb I would want at least as much free space as the size of my current database. If you are running both Tomcat and MySQL add a few gig for the backup that will be made of the old Tomcat files.
