I'm redeveloping a plugin and would like to make it easier for people to migrate the options and tables my plugin uses from one site to another, or to keep backups for themselves of these things.
Is there any general guidelines for this, or perhaps an existing plugin you can think of that implements this functionality well? I've not had any great luck finding this. Is there some reason this is not advised, or just not a popular option? Or I'm just looking in the wrong place!
I'm wondering things like if there is a standard sort of UI for import/export from a plugin, or if plugins hook into WP's own import/export for their personal settings and tables, etc.
Not looking for someone to do the work for me - but just for a point in the right direction. Thanks for any ideas.
