How to Migrate Old Perplexity Collections to Spaces

Perplexity introduced Spaces, a new way to organize searches, threads, and files in one place. Your old Collections remain in the sidebar but do not automatically convert to Spaces. If you want to use Spaces features such as shared workspaces, custom instructions, and file uploads, you need to move your saved threads manually. This article explains the exact steps to migrate each collection to a Space and what to do if your data does not transfer correctly.

What Are Spaces and Why Migrate?

Spaces is Perplexity’s replacement for Collections. A Space is a dedicated workspace where you can store related threads, upload files such as PDFs and images, set custom AI instructions, and share the entire Space with collaborators. Collections only stored thread titles and answers without sharing or file support. If you continue using Collections, your data stays accessible but you cannot add new threads to them. Migrating to Spaces unlocks the full feature set available in Perplexity Pro and Team plans.

Before you start, confirm that your Perplexity account is on a plan that supports Spaces. Free accounts can create up to three Spaces. Pro and Team accounts have unlimited Spaces. You also need a stable internet connection because the migration requires loading each thread from the collection.

Steps to Move Each Collection Thread to a Space

The migration process is manual. You must open each thread in a collection, copy or move it into a Space, and verify that the content transferred. Follow these steps for each collection you want to migrate.

1. Open your Collections sidebar
   Click the Collections icon in the left sidebar of the Perplexity web app or desktop client. A list of your existing collections appears. Click the name of the collection you want to migrate to view its threads.
2. Open the first thread in the collection
   Click any thread title to open the full conversation. The thread shows the original question and all follow-up answers with citations.
3. Copy the thread URL
   Click the share icon or the three-dot menu next to the thread title. Select Copy Link or Share Link. The thread URL is copied to your clipboard.
4. Navigate to Spaces
   Click the Spaces icon in the left sidebar. If you have not created a Space yet, click Create Space. Give the Space a name that matches the old collection name, such as “Research on AI Ethics”. Optionally add a description and set privacy to Private or Shared.
5. Paste the thread URL into the Space
   Inside the Space, click the text input area at the bottom. Paste the copied URL. Press Enter or click the send button. Perplexity loads the thread content into the Space. The thread appears as a new entry with the original question and all answers.
6. Repeat for every thread in the collection
   Go back to the collection, open the next thread, copy its URL, and paste it into the same Space. Continue until all threads from the collection are inside the Space.
7. Delete the old collection (optional)
   After verifying that all threads appear correctly in the Space, return to the Collections sidebar. Click the three-dot menu next to the collection name and select Delete Collection. Deletion is permanent and cannot be undone.

If you have multiple collections, repeat the entire process for each one. You can merge several collections into one Space by pasting threads from different collections into the same Space.

What to Do If Threads Do Not Appear in the Space

Several issues can prevent a thread from appearing after you paste its URL into a Space. Below are the most common problems and how to resolve them.

Thread URL Is Invalid or Expired

Perplexity thread URLs expire after a period of inactivity. If you copied a link from a thread you have not opened for months, the link may no longer load. Open the thread directly from the collection first to refresh the URL, then copy the link again.

Space Reaches the Thread Limit

Free accounts can store up to 500 threads per Space. Pro and Team accounts have no hard limit but performance may slow with very large Spaces. If you cannot paste a new thread, check the thread count by scrolling to the bottom of the Space. Delete old threads or upgrade your plan.

Thread Appears But Answers Are Missing

When you paste a thread URL, Perplexity imports the entire conversation including follow-up questions. If only the first question appears, the thread may have been truncated during the copy process. Open the thread in the original collection, scroll to the bottom to load all answers, then copy the URL again.

Cannot Find the Space After Creation

Spaces appear in the Spaces sidebar only if you are logged into the same account on all devices. If you created a Space on your phone but cannot see it on your desktop, refresh the Spaces page or log out and log back in. Spaces sync across devices within a few seconds.

Perplexity Collections vs Spaces: Feature Comparison

Item	Collections	Spaces
Create new entries	No (read-only after Spaces launch)	Yes
File upload support	No	Yes (PDF, image, text)
Custom AI instructions	No	Yes
Share with others	No	Yes (view or edit permissions)
Thread limit	Unlimited	500 per Space (Free), unlimited (Pro/Team)
Bulk export	No	No

Alternative: Export and Re-import Using Third-Party Tools

If you have dozens of collections with hundreds of threads, manual migration is time-consuming. As of this writing, Perplexity does not provide an official export or import tool for Collections or Spaces. Some users have built browser scripts that extract thread URLs from collections and paste them into Spaces automatically. These scripts are not supported by Perplexity and may break after updates. Use third-party tools only if you are comfortable with browser automation and understand the risk of data loss.

Conclusion

You can now migrate each Perplexity collection to a Space by copying thread URLs and pasting them into a new or existing Space. This manual process preserves all thread content, including follow-up questions and citations. After migration, you can upload files, set custom instructions, and share the Space with team members. For a faster workflow, consider using a browser script only if you understand the risks. Once all threads are in Spaces, delete the old collections to keep your sidebar clean.
