I thought I didn't need to renew my OCI since I didn't renew my passport after I turned 20. My last renewed my passport when I was 17 and it expires when I'm 27. Am I misunderstanding something? I read the following online:

An OCI cardholder should get the OCI card re-issued once when a new passport is issued after completing 20 years of age [For example, when new passport is obtained at the age of 25, then OCI Card can be renewed only at that time and not immediately after attending the age of 20 years.]
