Here is an article describing some points to consider, when moving from an older version to Firebird 3. It is a starting point for those who plans to upgrade their installations and wants to save from some headaches.
The survey about Firebird 3 installer is closed, and results are now published (see below).
Thanks to everyone who participated and contributed with comments and ideas. I hope the result will help guiding the Project about what people expect/wants from the official installer 😉
