If you're a partner, or you setup the site via partner.
A partner can log into their Partner Portal and change the plan for their client.
They goto Clients and view their details.
From here, click Upgrade Site.... then option is available to change plan.
I'm unsure if this option is available if they a Consolidated Billing customer?
Thank you mike, but my understanding is that this option upgrades to a paid site and I am not ready to go live yet. Please correct me if I am wrong.
Yes, that's my understanding too.
I haven't tried this before, but could you use the Create Site option in the Partner Portal which sets up a webCommerce 5 site; and choose the option to replicate from the existing trial site?
When you're ready to put the site live, you can opt to down-grade it to a webMarketing.
Only danger would be that you'd need to ensure you don't adopt any webCommerce elements (e.g. Web Apps, eCommerce) during the development.
Has anyone else ever done this?
