Planning to move hosts shortly, will tar up the whole pb install and export the database, anything i need to watch out for ? (i know vb used to have these weird cookie issues when you moved host).
That is only a problem if your cookie settings are specific to your old URL. The default cookie settings in xenForo are not specific to any one URL so this won't be a problem unless you have overridden the default cookie settings in the library/config.php file.(i know vb used to have these weird cookie issues when you moved host).
