LAZARUS SMARTUPDATER
The smartupdater allows you to update the database of any version of Lazarus or Advanced Guestbook (2.3 and over) to that used by the current version of Lazarus.
It does this by comparing your existing database tables with those used by Lazarus and then making the changes where necessary.
Once it has finished making any changes required it will optimise the guestbooks tables which can help improve performance.
Please note that if you have a database with a lot of entries it may take a while for the script to make any changes so be patient if nothing happens immediately.
