I’d like to better understand bulk connect using the mapping file. What’s a use case for that?

Hello Stefano,
It can be used for example if you move from one instance to another, and you would like to resume the synchronization with the same settings after moving to other instance.
Here is the support article for your reference: https://docs.idalko.com/exalate/x/6JMrAQ
And more detailed about bulk connect: https://docs.idalko.com/exalate/x/bQOOAQ
I hope this helps

Hi Mariia,
Thank you for you response.
It appears that there may be issues if the work management platforms are different from each other. Would there be any if I am moving from Jira to AzDo or viceversa?
Here is excerpt from the support article you sent across:
In case you’re moving data from one instance type to another, please make sure the Sync Rules work for your new platform.
I wouldn’t know where to check that the sync rules work for my new platform.
Bulk-connect - Also, based on your explaination why is it called bulk-connect? The expression Bulk-something makes me think of connecting one instance to many or many-to-many but I am be wrong. If that is also the case, would be the use case/need for connecting one instance to many or many-to-many?
Mapping file - Finally, I am also not extremely clear on how to generate/write up the mapping file because on the 2nd article you have shared it is only mentioned Jira whereas I’m working with AzDO. Any thoughts on that?
Thanks again,
Stefano
