The old system is:
- Windows XP Pro SP3
- Apache HTTP Server 2.2.16
- MySQL 5.1.50-community
- PHP 5.2.2
- Mantis 1.0.0rc2
- Windows 7 Pro SP1 32 bit
- XAMPP 1.8.3 (Apache 2.4.9, PHP 5.5.11, MySQL 5.6.16)
- Mantis 1.0.0rc2 (copied from the old system)
- some, but not all, issues displayed with empty description fields, although phpMyAdmin shows they are not empty
- some, but not all, issues with relationships display the following message one or more times in the relationships area:
Code: Select all
SYSTEM WARNING: Creating default object from empty value
Code: Select all

The Upgrading section in the Admin manual (http://www.mantisbt.org/docs/master-1.2 ... grade.html) does not mention any problems related to upgrading from a very old release like 1.0.0rc2. I was not able to find anything in the doc/wiki/forums that discussed big release jumps. Will the technique described in the Upgrading section in the Admin manual work cleanly, or are there some extra steps when the release being upgraded is so old?
