We have currently monthly indexes in the following format  
fabricxxx-access-log-monthly-2018.01  
..  
..  
fabricxxx-access-log-monthly-2018.04

We have decided to move away from monthly indexes to weekly indexes due to data compliance issues.

Can we leverage the "reindex-api" to convert the existing monthly indexes to weekly indexes ?

I have seen/read lot of questions on different forums, but they all discuss about how to convert daily indexes to monthly. My use case is quite the opposite.

Reindex api will work. You'd just include a date range filter in the `source` portion of the request, specifying a single week from the month. Then send it to a dedicated weekly index, and repeat for each week.
