Periodic meeting - change of schedule

Hello everyone, I've started using projeqtor for some of my work activities (I'm a software engineer and freelancer consultant doing project management for IT SMEs in northern Italy) and have a question about the periodic meeting feature:
I have a weekly project status meeting that was originally scheduled for Tuesdays, but now has to be rescheduled to Wednesdays, ~30 instances of the meetings happened already. Initially I thought of shortening the period in which the meetings were planned and to create a new recurrent meeting for the future occurrences, but apparently this fails without any error neither on the GUI or in the LOG (this might be a bug I should report).
How should I proceed to account for the change? Can anybody share what will happen if I change the scheduling of a periodic meeting? Will this affect only meetings that are in "recorded" status? Or will meetings in "done" status be affected as well?

Many thanks for this Free Software project which is the most complete tool for Project Management I could find, that covers also the usually very neglected (but very important) aspects of risk management and steering topics.
 

Thanks a lot for the prompt reply! I was hoping I could reschedule all the upcoming meetings at once through the GUI but I see this is not the case. (I can't use the multiple mode since I'd need to set each meetings' date to "planned day + 1" and not to a specific date).

Edit: I updated the future occurrences directly in the database and it was fairly straightforward (I'm not sharing the query to avoid copy-and-paste damages). On version 11.3.1 the meeting table is the one holding all the information: idPeriodicMeeting is the reference to the recurrent meeting; meetingDate, meetingStartDateTime, meetingEndDateTime, should be updated (this can be done through the date_add mysql/mariadb function).
