Support » Installing WordPress » Upgrading posts from Large WP 1.2 Blog to 2.0 with no downtime

  • I have a WP 1.2 blog at and have really hacked it with lots of custom code and added my own mysql calls to get it to do what I want

    I am now considering moving to WP 2.0 to be able to use some useful new plugins and WP features but I cannot afford any more than a few hours downtime because I earn a substantial amount of money from ads

    There are guides for upgrading from 1.2 to 1.5 to 2.0 on the WP site, but they assume that the upgrade is done on a live blog site and the blog will not work for several hours/days until the templates, options, plugins etc have been fixed

    I’d like to know if the following is possible:

    1. install WP 2.0.X to a different directory eg: /blog2/

    2. I’ll add plugins, categories, modify the theme and template, chmod files/directories, add my personal hacks, make changes to WP options etc to /blog2/

    3. somehow import the draft and published posts and comments from the MySQL tables used by /blog/ into /blog2/

    4. Once im happy everything works delete /blog/ directory and rename /blog2/ directory to /blog/

    Is this (or some other similar process) feasable?

  • you could take blog2 and justtell it to use the same sql database you use on blog 1

    If what you say is true than that would be fantastic!!

    I thought the database schema/tables/fields would have changed since so much time has passed between the release of WP 1.2 and WP 2.0.X

    PS for anyone in a similar situation. the DB tables are not the same in 1.2 and 2.0.3

    Waht I did was copy the 1.2 WP tables with a different prefix, ran the 1.5 and 2.0.3 upgrades on those copied tables, modified the theme and then renamed the new /blog2 directory to /blog and vice versa so there was no down time
