The article describes method of legacy program  systems analysis  which is proposed by authors on the base of legacy systems reengineering experience in the field of energetic. Estimates of module stability, algorithm of  module stability degree identification and module concatenation are considered. There are described method of legacy systems reengineering proposed by authors and expert system Expacy made for support of this method.Given in this article results  are  supported  by  RFBR  grants ╧ 10-07-00264, ╧ 11-07-00192 and by RAS Presidium Program grant ╧2.29.
