# Creating an Impact Report

The impact command takes both the new repository and the old repository, then generates a report that details the effect of merging the new repository into the old repository. The command line to build an impact report is as follows:

    ReqAdmin impact [-v] [-xml] <Path to incoming (new) repository> <Path to existing (old) repository> [Path and name for output file]

By default, the impact command function produces an HTML file with all of the results; however, an XML file may be produced instead by entering the -xml option.

Additionally, the report writes to an impact.[html/xml] file, but you can override this by giving a path and file name following the path to the old repository.
