Answer #1
  • This type of conversion strategy is called Parallel running.
  • She decided to turn on the new system and also continue to run the old system until everything is working okay.
  • Here both the new and old systems operate simultaneously.
  • The new system assumes the roles of the old system at this time.
  • When she comes to know that the new system is working properly, then the old system can be removed completely.
  • Then she needs to depend only on the new system.

Advantage:

  • An advantage of parallel running is that we can compare the old system and the new system and can ensure that the new system is working properly and without any errors.

Disadvantage:

  • In parallel running, both systems have to operate at the same time. So the cost of implementation, operation cost is very expensive.
