I can no longer escape the unavoidable... Despite no security issues whatsoever with my existing 1.3.8a based site (I have been super-careful about applying security patches and implementing each and every security tip), I decided to move on the 1.3.9h.

I decided to do so because the time has come to:
  1. Solve once and for all my PayPal Express Checkout problem.
  2. Get rid of a few unused add-ons while installing the greatest & latest versions of the majority of add-ons I decide to keep.


Now, I know that zc_install will take the entire database, as-is, and upgrade it to the latest version (so no data is lost and no installed addon settings are lost).

But since I installed a clean (no add-ons) version 1.3.9h as a base for my customization, I am wondering what would be the best strategy to import my existing data, including add-on data, from my 1.3.8a based store to the the 1.3.9h based one.

To be more specific, these are the add-on I currently have (the ones I intend not to keep, i marked with a greyed-out font):

  1. captcha_using_ttf__gd_v2-8_28-04-2007.zip
  2. local_sales_tax_mod_2.2.2.zip
  3. hidecategories_1-10.zip
  4. sitemapxml__formerly_google_sitemap_2-1-0.zip
  5. faq_page_v1-0.zip
  6. Ceon URI Mapping (SEO URL)
  7. Admin Profiles extension (AP)
  8. How Did You Hear About Us 1.3.8a
  9. Tabbed Products Pro 1.06


Is what I am trying to accomplish do-able?

If so, what caveats should I be watching for?

(I am aware of the need to repeat the tedious process of comparing files via WinMerge, since quite a few add-ons modify core Zen-Cart files).

Can I simply use phpMyAdmin to import to the new 1.3.9h store the .sql.gz file I export from the operational store (once I complete applying all the add-ons)?
