Maintenance Renewal or Professional Upgrade

My maintenance subscription has expired.
I have two options one to renew maintenance plan.
The other is to choose professional upgrade.

What is the difference between the two can someone explain?


The two options:

1. Maintenance Renewal of Home edition
Includes 1 year of free upgrades + support

2. Upgrade to Pro
Includes 1 (1 year of free upgrades + suppor) and the upgrade from Home to Pro

You can compare the Home and Pro editions here:
