Yes, you can transfer your domain to any registrar but only after sixty (60) days post-purchase.
However, you can start using the domain name immediately after you make a successful purchase from the premium offers. Some of the things you can do immediately include:
- Change Nameservers
- Create DNS Zone Records
- Create Custom Nameservers
The things you cannot do until your premium purchase is at least sixty (60) days old:
- Transfer the Domain
- Update WHOIS Information
- Get Authorization Key
- Lock / Unlock the Domain
* Once the domain has passed the sixty (60) days lock period, you will be able to perform all actions above.
