Znuny is a free and actively developed OTRS-fork. Existing OTRS ((free))-installations can be very easily migrated. LTS und upgrade-versions. Good documentation and helpful community; paid support available. I have migrated two old www-apps/otrs (6) installs which run very well. Reproducible: Always Steps to Reproduce: 1. download source 2. follow instructions 3. install to replace OTRS 4. run Actual Results: replace/upgrade exisiting OTRS ((free)) installations. This is an ebuild-request (i hope this is the right place). OTRS from OTRS.com (www-apps/otrs) has left portage a very long time ago and their release-model ist not (really) Free anymore. I have not created an ebuild but installed it from source. (I am not affiliated with znuny in any way.)
