Synchronization between two database tables

Hi
I have two databases, dB1 "tonerfox_gr" and dB2 "tonerfox_solar." Both have a table called "configuration." The "configuration_value" field has "configuration_id=2242." In this "configuration_value" field with "configuration_id=2242," the last number of the receipts created is entered. My problem is that when number 132, for example, is created in dB1, the number in the table changes (due to the script) to the next 133, but not in the dB2 database. I then always have to check which number is the last in the dB1 database, i.e., 133, and then manually enter the 133 in the dB2 database so that the next invoice can be created in the other shop with the number 133. Is there any way to synchronize this so that the "configuration" table of dB2 takes over the value of the "configuration_value" field of the dB1 table if the field "configuration_id=2242"?
