This task is simple. We have a MantisBT (www.mantisbt.org) installation on a GoDaddy host. We are running version 1.1.7 and want to upgrade to the latest (1.2.19). The automated process didn't work as expected. So we need someone to go in and get it done. We want to preserve all the old content. It has to bee working perfectly fine (except for bugs in Mantis itself), users need to be able to continue accessing their same queries as before, open new issues, upload and download files, ensure Mantis can send email notifcations, etc... You will get the old database and you can prepare the new installation in whichever way you think is adequate. However, you may not bring down the current system for more than a few hours to avoid blocking current users. But you are free to experiment on the server separately if needed. There should be no real "development" in this task unless you need to write some scripts to migrate the data or convert formats.
