Following is a response from Senior DHS Stata Specialist, Tom Pullum:
If you are using Stata, then the "egen group" command will probably be easier and safer than adding 1000, or 2000, etc. If you are not using Stata, then adding those numbers may be easier. You do not need to do any manipulation before appending the files, so long as you have a unique identifier for each survey, as I suggested. So long as you have a "survey" variable or other unique identifier, you can do all your survey-specific edits, etc., AFTER the appending. Note: do not rely on v000 or hv000 as survey identifiers. There are many cases of two different surveys, conducted close together in time, having the same values of v000 or hv000.
