When it comes to upgrading Tiki, there's no one-size-fits-all approach. As discussed with other Tiki developers, there are various methods to upgrade. Some prefer to stick with Long Term Service (LTS) versions for as long as possible, making occasional significant upgrades. Others choose to migrate existing files from version to version and some use fresh versions and clone theme, language files, templates, database and files. In this article, I'll draw from my extensive experience in using, providing support services, and developing with Tiki Wiki CMS and explain my detailed process for upgrading a customer's Tiki from one stable version to another.
