As of now, there is the ability to re-import data from SMF in a limited manner, this time running the SMF data through a better input converter. This should fix many of the issues in old posts with corruption due to failed import. However, it will necessarily result in the loss of any edits made to the re-imported posts since the move to XF. It is possible to do this by small parts, choosing which posts to overwrite and which to leave. However, it's not easily possible to tell which posts have valuable edit data which should be retained, and which can be overwritten with their SMF versions. Moreover, once a post has been re-imported, to revert it will require a restoration from backup, which is an onerous procedure. Thus, asking the userbase: how many of you have made significant edits to old posts since moving to XF? If edits were made only in order to fix import errors, would re-importing in order to make the posts match their SMF version be acceptable? Would it be a problem if those edits were lost, to be replaced with the properly-converted contents of the SMF database? In order to resolve the archive issues, it's very likely such a re-import will take place. However, doing this it's possible to exclude posts at almost arbitrary granularity. Anyone desiring such should particularly note it here.
