change all shared calendar entries from assigned user who leaves company

[k26]

A user has created a lot of entries into the calendar that must be shown in the shared calendar view
The user leaves the company.... and is deactivated.
All the entries from calendar are missing....
How can we reassign in mass all the entries from this original user to a new one ?
Thanks for support.

You can use Searching on the list view and MussUpdate features.
