I installed X on an account where I have previously built posts with both the classic editor and with Gutenberg. I’d like to consistently use Cornerstone going forward including on old posts. Whenever I go to an old post and select editing with Cornerstone there is no content to edit.
I have checked permissions and I think those are OK.
Is there a way to migrate old posts and pages so the Cornerstone can edit them. Please share advice or links to documentation. I have been unsuccessful finding anything that pertains to the current release.
Thanks.
