Upgrading Plone 3.3 to Plone 4.3

Recently we upgraded a Plone 3.3 site to 4.3. Here are some thoughts regarding this.

Recently we moved a site from a long-time customer to Plone 4.3.

First off, the list of step to follow in were quite exhaustive. There were some things that we did differently:

  • We went straight from Plone 3.3 to 4.3.3, skipping the intermediate versions (4.0, 4.1 and 4.2). For our site this worked.
  • After that, we ran all upgrade steps at once.
  • We had to manually remove some Javascripts (mostly Kupu) from the registry, in order for TinyMCE to work.

The sooner you upgrade to a more recent stable version, the smaller the hassle. Also, there’s a performance improvement (see image), and some nice new features. See for more reasons to upgrade.

We love code
