How to resolve the template page limit and template switch?

Site URL: https://www.nadinepfeifer.de/

I have redesigned my website and now two questions have arisen:

1. I would love to show more of my work in my portfolio. 
Unfortunately there is a limit of pages. Is there an option to have more pages in my template?

2. Is there an easy way two change the template design without crushing my website?

You can have up to 400* pages on a Squarespace website unless your site is on a very old "legacy" Personal plan, in which case there's a 20-page limit. To learn more about legacy plans, visit Legacy billing plans. If you're on a legacy plan with page restrictions and you want to expand your site, you can switch to a current Personal, Business or Commerce plan.

Page limits are defined by your billing plan, not your template. However, more information on changing your template, see Switching templates.

*A site can have up to 1000 pages, but Squarespace don't recommend more than 400 due to performance reductions.

The current personal plan has no page limit and no code injection which I have a lot of in my 20-page site. So if you have that as well and you switch plans to the current personal plan, things may break. To get the same coding features as our old personal plan you would need to upgrade to a business plan.

You have a nice nice-looking Avenue site. There are many of us using that classic template. If you want to show more of your latest work, consider making a new gallery or layout page and rotating an old one out of the index, into the unlinked section of your site, disabling it, enabling the new one, and moving it into the linked section to take its place. The old one will just sit there until you want to use it again. I do this quite often just to have some fresh content. I also combined my About and Contact on the same page to free up one to use for something else.

Hi paul2009,

Can you explain how to upgrade a legacy billing plan to so that it no longer legacy plan and no longer has a 20 page limit. When I go to the option for changing the billing plan it only offers to upgrade to a business plan. Can I just update to a current personal plan that would not have a 20 page limit?

To switch to the current version of the same plan you're on (a legacy Personal plan to the current Personal plan) you'll need to open a ticket with Customer Care so they can help.

Will upgrading affect my website in any way?

It should not. I will just change the configuration features, if upgrading to business, if changing from the old personal plan to the new one, yes things could happen to your site especially if you have header and footer code injection.
