Following is a response from DHS Research & Data Analysis Director, Tom Pullum:
This kind of question has come up many times on the forum. If you search with keyword "pooling" you should find answers to your questions. The postings describe options for the weights and how to handle the construction of clusters and strata that distinguish one survey from another.
When you have a pooled data file, you include a categorical variable for "survey." Then you basically treat survey as a covariate, much as you would treat v024 or v025, for example, in the analysis of a single survey.
