  • WPOso


    I’m not using WordPress yet. Rather, I have a series of websites I designed myself. They’re essentially one big CMS, with static pages on MySite2, MySite3, etc. linked to a series of includes on MySite that handle the preliminaries, database queries, etc.

    I’m now planning on combining all my sites into sort of an encyclopedia that functions something like Wikipedia. I won’t delete the other sites; rather, articles will be available at the original URL and at the new location on MySite/Geopedia.

    To get to the point, I’m wondering if it’s time to upgrade to a CMS, like WordPress or Drupal. I have a thousand questions and will have to download and install both and play with them a while. But here’s one question I’d like to ask now…

    I have a pretty big series of database tables with articles about a wide variety of topics – mammals, birds, plants, symbols, politics and on and on. If I want to upgrade my sites to WordPress, am I going to have to modify these DB tables, or do I need to let WordPress create new tables, then copy the articles from my original tables to the new database?

    I think I need to retain a series of tables, rather than put all my content in one table because of size limits. I tried importing a local table into my online database recently and got a message that it was too big. (I’m using PHP and MySQL, by the way.)

    Sorry for the rambling question. I’d just like to have a better idea of what lies ahead for my particular project. Thanks!

    P.S. My primary website is (soon to change to, and you can see an example of one of its child sites at
