However, with calendarserver 5.x, I can see that these kind of guids are considered invalid. Now, I figured out that the valid guid can be generated from the function 'str(uuid4()).upper()'. But how do I migrate the data from older guids to the newer guids? Is there any database update command that I can run?

Ok. So, is there any workaround (easy or difficult) for users who are 
now using xml directory with invalid guids? I mean as soon as they 
upgrade to 5.x from 3.x or 2.x, all their data would no longer be 
accessible. What can be done to fix this?

One workaround that I could think of is to comment out the line "assert 
len(name) > 4, ..." in twistedcaldav/directory/common.py while compiling 
but I am not sure if it is such a good idea.

Kindly advise on what is the best approach.

What would the url be like? For calendar, I have been using 
http://calenarserver:8008/calendars/users/<user>/calendar/.
