Hi Erik,

You should be OK doing so, although there are some differences between the two themes (the Prologe having more features and options). This will normally be true for switching themes, in general, from any source.

One thing you can do if you decide to change themes is to use a backup plugin to make a backup of your website. Normally when you change themes and decide to revert back, everything should fall into place as it was. For Prologe, if you decide to switch to it, you will have some options to adjust. Your content should be OK though.

Best Regards,
Andre

Good to hear you planned on a backup! For differences between Twenty Twenty and Prologe Lite (especially the premium version), there is no specific comparison list available, but the construction of the theme is different and of course, more features with the Prologe theme. With Prologe Lite vs Premium, this can be found here:

If your website is a simple site as you described it, you shouldn’t have (if any) issues.

One thing to keep in mind is that if you decide to go for the premium version, this gets installed and activated as a new theme. However, most of your settings and options set from the Lite version will be inherited into the premium one–I usually tell people to make note of any option settings before the upgrade so that you can re-enter them if necessary; things like colours for example.

As for Gutenberg block plugins, it depends on which ones, but you should be fine overall. The only way to know is to try it out.
