Prismm, the tool many planners and venues still think of as AllSeated, is being retired: it goes view-and-export-only on October 1, 2026, and closes for good on December 31. If you’re looking for a Prismm alternative, you probably have a more pressing question than how competitor tools stack up on paper. You need to know what happens to your seating charts, floor plans, and guest data when Prismm goes away, and how to move your active weddings without losing the time and effort you’ve already put in.
This guide walks through the sunset timeline, what to export, and how to migrate to Folia so your plans don’t skip a beat.
The Prismm sunset timeline
Cvent acquired Prismm in April 2025, and has begun winding down the standalone platform. Existing customers are being pointed toward Cvent Event Diagramming (formerly Social Tables). The catch is that templates, favorite objects, and object groups don’t move with you, and events dated before January 2022 can’t be accessed in the new tool at all. If you have older events worth keeping, export them as PDFs before you lose access.
The transition runs in three stages. Your exact cutoff is account-specific, so treat notices in your Prismm dashboard as the source of truth.
| Date | What changes | What to do |
|---|---|---|
| July 8 to September 30, 2026 | New event creation ends, with at least 30 days of notice | Check your account notice and stop starting new weddings in Prismm once your cutoff arrives |
| October 1, 2026 | Prismm becomes view-and-export-only | Finish any essential edits, then export the layouts, reports, and data you need |
| December 31, 2026 | Prismm shuts down | Confirm every file you need is saved before this date |
The timing above matters most for weddings still in progress. A chart that looks finished today can still change after a late RSVP, a revised meal count, or a venue layout adjustment, so give yourself room to export once those details settle.
What you keep, what you rebuild
It’s easy to export your active Prismm work, keep final reference copies somewhere safe, and move any active weddings into Folia. Here’s what that process looks like piece by piece.
| Your Prismm work | Save/export this (edits lock Oct 1) | In Folia |
|---|---|---|
| Guest and meal data | Names, RSVPs, plus-ones, dietary notes, and meal choices, exported to a file you can reuse | Bulk import and set up in the guest list; meal choices carry straight into the seating chart |
| Floor plans | Room dimensions, table positions, and fixed elements like bars, entrances, and the dance floor | Upload the plan as a reference and place your tables on top of it |
| Seating charts | Table and seat assignments, plus a PDF or image of the final layout | Rebuild the working chart with drag-and-drop tables |
| Saved templates and libraries | Screenshots and notes as needed (these don’t export/transfer anywhere) | Recreate your preferred workflow as you rebuild your first wedding |
| Completed weddings | Final charts, floor plans, and reports | Archive them outside of Prismm to keep on hand as needed |
How to migrate to Folia without losing active wedding work
Moving doesn’t mean rebuilding every past wedding. Start with active events, then upcoming ones, and archive completed work last.
- Export and archive your Prismm work. Begin with the weddings that still need edits. Save the seating chart, floor plan, guest list, meal information, final reports, and any client-facing PDFs. Grab both the data and a visual copy of each layout. Use a consistent file naming system (such as Smith-Jones-2026-09-14-Reception) so the right version is easy to find when you rebuild it.
- Choose one active wedding as a pilot. We recommend not moving your whole roster in one sitting; pick one wedding with a manageable guest count and a clear plan to start. Rebuilding a single project first shows you what transfers cleanly, what will require additional manual work, and which settings should become part of your standard process going forward.
- Rebuild the guest and meal data first. Set up the guest list before the seating chart; confirm each record has the guest’s name, household, RSVP status, plus-one, meal selection, and dietary notes. We’ve made it simple to migrate these details using your Prismm csv export in just a few clicks. Folia’s guest list is built to manage RSVPs, meal choices, plus-ones, and addresses in one place.
- Recreate the floor plan and seating chart. Using your Prismm export as a point of reference, upload the floor plan, add your tables in their specified shapes and sizes, and assign guests. Meal selections appear as color-coded chips at each seat, pulled directly from the guest list, so your catering team can easily read the room at a glance. Be sure to compare the Folia version against your saved Prismm file before sharing it with the couple or venue.
- Invite clients and standardize the process. Once the pilot is confirmed accurate, invite the couple to their personalized Folia portal with view or edit access. From there, you can turn the repeatable steps into a process: your preferred guest fields, meal categories, timeline structure, naming conventions, and export steps: each wedding becomes faster and easier to build than the one before.
What to look for in a Prismm alternative
Judge a replacement by the work it saves you, not by the feature count on its pricing page. When you’re replacing a tool this central to your workflow, some things matter more than others:
- Does the guest list feed the seating chart, or do RSVPs and meal choices have to be entered twice?
- Can you manage several weddings at once in separate workspaces?
- Can clients access their own wedding details easily, with permissions you control?
- Can you export finished charts cleanly for vendors and venues?
Folia brings guest management, seating charts, meal tracking, timelines, vendor tracking, and client access into one planner workspace, with meal selections flowing from the guest list into the chart, which is the piece most planners are trying to protect. Still, no two platforms are identical, so it helps to know where Folia is a strong fit and which gaps to check for before you switch.
| Folia fits well if you want | Verify first if you rely on |
|---|---|
| Guest, meal, seating, timeline, and client tools in one place | 3D venue walkthroughs or virtual tours |
| A separate workspace and private portal for each couple | Imported Prismm object libraries or saved templates |
| Client access with view or edit controls | A one-click file import from Prismm |
One thing to keep in mind: Folia is a 2D planning and seating platform, not a 3D venue-visualization tool. If Prismm’s 3D walkthroughs were central to how you staged or sold events, consider that factor carefully before migrating.
Frequently asked questions
Can I import my Prismm seating charts directly into Folia?
Not as a one-click transfer. Export the chart and its guest information from Prismm first, then rebuild the chart in Folia using that export as your reference. Guest and meal details move fastest, while the visual layout is recreated on Folia’s canvas.
How long does it take to move a wedding to Folia?
Most planners can rebuild a wedding in a single focused session. Re-entering guest and meal data from an export is the slower part, but the seating chart comes together quickly once the floor plan and guest list are in place. Starting with one pilot wedding will give you a realistic sense of timing before you move the rest of your roster.
What should I export before Prismm access changes?
Prioritize active seating charts, floor plans, guest lists, meal summaries, reports, and final PDFs. Save the underlying data, not just the visual. Templates and object libraries don’t migrate anywhere, so capture them as screenshots and notes while you still have access.
Will my clients need to pay for Folia?
Couples reach their own wedding workspace through your plan, at no separate cost to them. Your subscription covers the planning tools for the weddings on your roster.
Take the next step
The Prismm shutdown doesn’t mean abandoning your planning history or rebuilding every wedding from scratch. Confirm your account’s exact cutoff, export your ongoing work, test migration with an active wedding, and check the features your workflow depends on before you commit the rest.
Folia’s all-in-one wedding planning platform keeps guest management, meal choices, seating charts, timelines, vendor tracking, and client access in a single workspace. If that matches the way you run your weddings, we’re here to help you take the next step.
