It will NOT be possible to automatically upgrade to the 1.2.0 release from the 1.0.x or earlier releases. Upgrades from earlier releases is a detailed manual process. You may contact firstname.lastname@example.org to inquire about contracting for the necessary support if you need to perform such an upgrade.
Upgrade processes are developed as needed and will be documented in this chapter as they are created. If you need an upgrade process developed you may contact email@example.com to inquire about contracting for the necessary work.
So far we have developed a 1.2.0 to 1.2.2 upgrade process and it is documented here. Other upgrades like 1.2.0 to 1.2.1 and 1.2.1 to 1.2.2 would follow a similar workflow but have not been tested and will almost certainly be missing some database schema and data updates.
