Thanks for replying and the provided link. I know how to change the plan.
My question was if I am able to go back to the "photography plan" in case I don't get along with the "lightroom plan". The reason I am asking is because I thought the photography plan and lightroom (desktop version) are legacy products.
Stay exactly where you are. The Lightroom plan is LESS than what you have now. And if you attempt to change plans mid-way through your annual subscription, you will incur a 50% early cancellation fee. There is nothing to be gained from doing this.
Photography Plan includes the very latest versions of these products & services: -- Photoshop CC and Photoshop on iPad -- Lightroom CC on desktop, mobile and the web -- Lightroom Classic -- Portfolio website + hosting -- Spark with premium features -- Bridge -- 20 GB cloud storage (upgradable to 1 TB). https://www.adobe.com/creativecloud/photography.html
Despite what you may think, Creative Cloud storage is not a replacement for hard disk space. Always maintain file backups on HDs, externals and dedicated cloud backup services like DropBox or Backblaze just in case the unthinkable happens. Otherwise, you risk losing all your work which is no fun.
