sometimes we add new properties to long ruining events.
for example add “page_title” prop to “Page View” event.
and of curse its will be show as undefined when this properties was not exists in the past.
is it possible in any way to update old/existing events with the new property?

Unfortunately, the short answer is no. Our events are immutable - meaning that once the event has been triggered, we cannot change the data.
That said, have you taken a look at our beta for Lookup Tables? If you have a page ID for instance, that you can map Page Title to, you can use look up table to append the data after the fact. It works like vlookups in Excel, if you’re familiar with that. Have a look at the documentation and the video, and see if it’ll help answer your need!
