Do you mean, you reformat the disk and install the new version of the OS? On the same machine? In that case, if the architecture is the same, no data conversion is needed - the data in the databases can just be used directly.Richard Megginson wrote:One of the big issues is cross platform migration e.g. going from FC-5 i386 to F7 x86_64. There are a number of issues involved with this. We are trying to figure out the best way to do this and we need your help. If you could, please read the section about cross platform migration - http://directory.fedoraproject.org/wiki/DS_Admin_Migration#Cross_platform - and let us know what you think, especially if you are an admin who will actually be using this in a production environment.I'd guess the "worst-case upgrade" is a single directory server deployment where a cross platform upgrade could imply only 1 host is available for reformat? If so, doing a "Local Source to Remote Target" migration doesn't make much sense. In such cases, an export to ldif first, backup/ reinstall / restore "/opt/fedora-ds" and then do the upgrade against the restored data seems like the best way to do things.
Sure, but there are some cases where folks will have multi-GB databases on old machines.Multi-directory-server sites probably have spare hardware kicking around - I wouldn't worry about wasting disk space ;-)
