How Long Does A CMS Migration Take?
BeginnerQuick Answer
TL;DR
A CMS migration typically takes 4-16 weeks for small to mid-size sites, and 3-12 months for enterprise platforms. Key factors affecting timeline include content volume (hundreds vs. millions of pages), content complexity (custom fields, relationships, multilingual), number of integrations to rebuild, and team availability. Simple blog migrations can be done in days, while enterprise Sitecore or AEM migrations may take a year or more.
