Move events from one calendar to another?

[annk]

Jeg har various Google and iCloud calendars synched to iCal. One of them, the Microsoft Exchange calendar I used at work, is no longer active (I quit in January 2019), but even though I no longer have access to make changes in it, I've kept it visible because it contains a record of the clients I've had in private practice. (This private practice overlapped with my last few years at my former employer - should have made a separate calendar for private clients, I can see this now.)

So the thing is that I'd like to delete that calendar from my system - it keeps asking me to log in, which I no longer can - but I need to preserve the information. Ideally I'd like to batch move events from that calender over to an iCloud or Google calendar. Is there a relatively easy way to do that?

Thanks in advance!

Thank you!

I just followed the instructions there to export the work calendar info, import that info into my current calendar, then unchecked the original work calendar. I'll take a look on my iOS devices and see if it everything seems to show up in the combined calendar.
