Best Approach for migrating data and attachments from ServiceNow(Dev) to ServiceNow(PROD)

[Akhtar Rasool]

Dear All,

I have migrated some data(records in lakhs and many attachments) from 3rd Party tool to ServiceNow Instance using REST API through Mid Server.

The Data is currently in DEV instance of ServiceNow, i would like to know if there is any best way to load the data along with attachments from DEV to PROD without affecting the performance or resources of PROD(if any).

Import/Export doesn't work as the records are in huge number, breaking the bulk records into to small chunk will take lots of time.

Jonsan, I manage to use "base64Encode" and was able to attach the file from one SN to another SN.
