At times like these, the existence of a good backup and recovery strategy is paramount.  In the case above, the creation of a backup before the change would have been a good idea.  The old information could be restored and the change could have been applied again – except correctly this time. Backups are good; knowing where to find the backup is even better.  There is no use in making a backup if no-one knows where to find it or how to use it.  At CoreSolutions, one approach that we use to help with these mis-steps is whenever we install a new application, we highly recommend installing a sandbox at the same time. If there are changes to be made to an installation, always try it on the sandbox first.  If it doesn’t work, make some changes and try again.  The sandbox is a proving ground for your change – by changing the sandbox first, you eliminate much of the trial and error that is associated with product changes and upgrades.
