Common issues

  1. It only has a simple conversion tool provided by Microsoft, the conversion rate is low, the cost is high, and quality is poor.
  2. Because there is a simple conversion tool provided by Microsoft, people assume that the migration will be easy.
    Quality and delivery deadlines cannot be met due to insufficient man-hours for migration and testing.
  3. Because do not understand detailed technical points, many modification and testing points are missed.
  4. Many migration companies are Unable to conduct business function tests, leaving the tests up to the users means without pinpoint test, although a lot of test, quality is poor.
