Since the users already started using the previous version and had messages stored inside, we needed to migrate all of the data to the new version without taking the old one offline. All of this was seamlessly done in one month. Since everything was done inflight, we needed to validate the databases to make sure everything was transferred correctly i.e. each conversation correlated with the right user. This involved creating a validating application to compare the source and destination for discrepancies and inconsistencies.
In the end, all of the data was transferred without loss or corruption. Also, we had rigorous security measures in place to ensure that the data remained secure during the migration. Both Vigilo and their customers were very happy with the end product and the childcare management chat is used today to connect everybody involved with the educational process.
