Background:
Two data bases physically separated each with two Projects.
One Project is used to collect all the bugs raised in the other Projects.
The mechanism used is that the Projects export their bugs to csv.
The one Project imports the bugs using those csv files.
Problem:
The key used in the different Projects sometimes overlaps so when importing the bugs overwrite each other where the key matches.
Question:
How do I overcome this so I can import the bugs and update those bugs imported from other Projects without overwriting
