We have requirement where we have exported the data from Confluence Data Center version to Confluence Cloud Version, import was completed with no issues, however on the pages we see the option which says "This page can be converted to the new editor", "Some page elements aren't supported in the new editor". We are able to continue our work ignoring this message. Which means we are doing edit in the legacy editor. My query is if we continue using old editor and do not convert the pages, will there be any issue in future on those pages?
