There have been a lot of questions regarding usability of past assets on the new sheets. The FAQ section on the new sheet landing page has been updated to include a lot of recent questions. Your answers should be in here:
When can i expect the full release of the new character sheet and builder?
The new character sheet and builder will be available the same day as the D&D 2024 Player’s Handbook: September 17.
How do i try out the new alpha character sheet?
The alpha version of the character sheet is available on Roll20 Characters.
Do i have to be a subscriber to access the alpha?
No, the Alpha character sheet is open to everyone.
Which compendiums are compatible with the new sheet?
The new character sheet and builder will be compatible with all D&D 5th edition sourcebooks and adventures, including the new D&D 2024 core rulebooks.
How do i give feedback or report a bug?
Send us your feedback form via the button on the sheet for suggestions and bugs.
Is this the full character sheet experience i should expect in September?
No, there is plenty more coming for both the Beta release in July and the full release in September.
Will the existing D&D 5th Edition (2014) sheet be removed?
No, there are no plans to remove the existing character sheet from Roll20.
Will i be able to use my older books already purchased on Roll20?
Both the 2014 and 2024 books will be within one compendium (similar to how Pathfinder 2e /Pathfinder 2e Core works), so you'll be able to access both in a campaign.
Will i be able to create 2014 characters with the 2024 sheet?
Yes! You'll be able to create characters using either ruleset with the new 2024 sheet and builder.
Will i be able to continue to manage my existing 2014 characters with the 2024 sheet?
We are working on tools to convert your characters from the old sheet to the new sheet, if it's desired, as some 2024 functionality will not work with the old sheet.
Will monsters, spells, feats, etc. From the 2014 sources be usable and manageable with the 2024 sheet?
Yes! You'll be able to utilize 2014 items, weapons, monsters, feats, etc. with the 2024 sheet, and in some cases you'll get additional functionality if you use the new sheet.
Are the new D&D 2024 books any good?
Some of the Roll20 team have gotten the chance to read advanced copies of the new Player’s Handbook. We think it is the biggest and best version of D&D ever made. (No really, we don’t have to be Mark Hamill promoting the Last Jedi.)
