Systems generally do not store data in the same way. Field names may be different, or data may need to be manipulated, combined or split apart to fit into the other system. The most important part of an integration or migration is mapping this data appropriately. The old adage of measure twice, cut once is just as true in technology as in carpentry. We start our analysis by building a thorough understanding of the data in each system and end when every piece of information has a comfortable home.
Once an integration is up and running, it is largely invisible and issues may not show up until well after they occur. We constantly monitor system health to make sure all data was accurately moved and accounted for. You can enjoy peace of mind knowing that alerts are immediately sent if an issue arises and even if all goes well.
