A one-time migration is a process of transferring data from one database to another which is done only once. On the other hand, a continuous migration is a process of transferring data which is done on a periodic basis.
For example, in a one-time migration, a company might need to transfer all its existing customer data from an old database to a new database. This would occur once, and then no further data migration would be necessary.
In a continuous migration, the company would be transferring data from the old database to the new database on a regular basis. This could include transferring new customer data that is added to the old database, as well as any changes to existing customer data.
The main difference between the two is that a one-time migration is done once, while a continuous migration is done on a regular or periodic basis.
