Hi ranesky,
According to your description, I understand that you want to upgrade the subscription from Office365 P1 plan to Office 365 Small Business Premium Preview.
Before moving on, I want to confirm some information with you:
1. Have you received some Office365 upgrade emails from Microsoft?
2. Is there some related information in the Office365 portal?
In the current few weeks we are trying to bring the newest version of Office365 to users. The upgrade is based on the region, so once the upgrade is started in your region, the global administrator will receive the upgrade email. If you have not receive the related email, I suggest you wait until it start in your region. Of course, I would like to keep close with you to solve the problem as soon as possible if you have.
Thanks for your understand.
Best Regards,
Eben Liu
