Existing Office 365 P1 Plan and New Small Business Premium Trial

Hi,

I have an existing Office 365 Account (P1) which has my existing Website domain etc and it works well! Although the Hosting Support at Melbourne IT leaves a lot to be desired.

I have just signed-up for the Office 365 Small Business Premium Trial under a new username and I have created a new website which has its own domain name in sharepoint (different to my P1 domain),

I would like to keep both websites and plan to change my existing P1 Website to the one created in the SB Premium Trial in time as the new website editing and design tools are so much better, and I believe I would not have to have my domain hosted at Melbourne IT (is this correct?)

What are my options?

Obviously I do not want to pay 2 subscriptions, but what will happen when my SB Premium Trial runs out in 25 days time? Will I lose the domain and website created here if I do not subscribe to the SB Premium Plan?

Can I transfer the website created in SM Premium Trial to my P1 Account - even though it has a different username? or can I transfer the P1 website to the SB Premium Plan?

I woud like the option of having the Office suite on a number of Mac products that I have - is this an option with the P1 plan going forward or would I have to upgrade to the SB Premium Plan?

Many thanks in advance for help on this matter.
