The top 5 strategies to ensure a successful transition into a shiny new system are as follows:Aim for automated migration solution: Legacy system migration is often viewed as a one-time activity and developers end up going for manual actions hoping to execute them for only one time.

Manual actions can significantly slow down the operations and even if it is a one-time operation, manual actions should not be adopted.

At the beginning of the project, an entity-level plan must be created so that there are no surprises for later on.

The migration approach will define whether the data will be loaded in one go or will be loaded in small batches every week.

Check data quality: Even if there are no data quality issues reported from the legacy systems, the quality of source data should not be overestimated.

The data can be so historical that it may not be touched for a long time but could be activated while transferring to the new system.
