PURPOSE:To estimate in advance a processing time of a migrating destination at the time of migrating a migrating part of a structured system divided into a migrating part and a non-migrating part. CONSTITUTION:A processing time calculating part 71 takes a difference of a migrating origin processing time (a) and a migrating origin non-migrating part processing time (b) measured by measuring parts 1, 2, and outputs a migrating origin migrating part processing time (c). A performance ratio calculating part 72 takes a ratio of a migrating origin system performance value (d) and a migrating destination system performance value (e), and outputs a performance variation rate (f) after the migration. An estimating part 73 multiplies the values (c) and (f), and calculates a processing time (g) of only a migrating part in a migrating destination. A measuring part 6 inputs a non-migrating part use condition (h) from a measuring part 5, and outputs a processing time (i) in a non-migrating part in the migrating destination. An estimating part 74 calculates a processing time (j) of a migrating destination system by taking the sum of the values (g) and (i). |
