E-Samudra keeps an applicant informed by updating the "Application Status" column of the APPLICATION STATUS Table. I applied on 9th May 2019 and sent my Original CDC on 10th May 2019. To me it seems like MMD starts to process the form only after receiving the original old CDC !
I received email feedback with "Kindly Upload The Biodata Page Of The Cdc Booklet Within 03 Days" on 14 May 2019. I later realized that I missed scanning my address pages in CDC (Took "last 2 pages" too literally ! Thankfully I had a scanned copy of all pages with me. Lesson learnt was that before sending original CDC have copies of all pages with you, just in case you need it !
I uploaded the required pages on 16 May 2019 and by 19 may the application status changed to "Application approved". MMD Speed-posted my new CDC on 21 May 2019 which I received on 24 May 2019. So overall you should get your old CDC replaced with new one within 15 days !
You will receive your old CDC punched and stamped "Not for service but for reference only". There is also an acknowledgement slip which is requested to be acknowledged as receipt ! While a simple online acknowledgement would be much easy sending a filled slip, back, seemed quite impractical ! I did not acknowledge it ! Practically MMD can track speed-post status too from the India Post portal if they needed to !
If you found Indian CDC Replacement procedure helpful, please do share it.
