When data migration goes wrong

With migrating to the cloud increasingly becoming a necessity, it is imperative that organizations pay greater attention to effective data migration.
Numerous surveys in recent years regarding data migration.
A post-in-depth analysis revealed that many organizations went way past their budgets and schedules during data migrations.
Not even two-thirds of companies managed to complete their migration projects in time and within the allocated budget.
Furthermore, the post-survey analysis revealed some common factors that resulted in this disparity.
The factors :
+ Lack of pre-migration planning
+ Failure to clearly envision the post-migration environment
+ Lack of specialized technical skill set to perform the migration
+ Failure to properly scope out the required costs and time
+ Improper #backup for delayed schedule
+ Inefficient project management skills specifically pertaining to migrations
