the topic describes my question already. As we are using gitlab issues also for non-devops things mattermost boards/cards might be a better choice due to their higher flexibility in setting them up (AFAI understand). Therefore, it would be nice to be able to ex- and import. So far I only found documentation for this with respect to apps like Trello, Ansana etc.
Heya Said! At this stage, I would say it’s probably looking unlikely due to the current support status for Mattermost boards, but it’s possible someone else in the Community might be able to offer up some good advice!
