Go and try searching for “migrate 20 dynamodb tables from singapore to Mumbai” on google and sure that you will get mostly migrating between accounts. But the real pain is that even though the documents say that full backup and restore is possible, the table has to be created with all the inherent configurations and when number of tables increases like 10 to 50 it becomes a real headache. I am attempting to automate this to the maximum extend possible using couple of shell scripts and a javascript code to rewrite exported json structure to that of a structure that can be taken by create option in the aws cli v2.
