When you transfer your domain to Z.com, your current domain plan will be automatically extended by one year.
In that case, the expiration date with Z.com will be forwarded by one year based on the expiration date with your previous registrar once the domain transfer is completed.
For example,
- With the previous registrar,
Domain start date on 31-Jan-2020
Domain expiration date on 31-Jan-2021 - Transfer to Z.com,
Domain transfer date on 01-Jan-2021
Domain expiration date on 31-Jan-2022
*Kindly note that the above scenario may not apply if the domain you are transferring has passed the expiration date.
