Move data from one table to another table with index match??

[cknnugget]

I am trying to match data from one table (ETAtable) to another (DBtable). All the macros I've attempted have failed.
DBtable is the database. DBtable size is 10000 rows by 64 Columns with new entries added daily
ETAtable is the data entry table. Users use this table to enter ETA dates.
DBtable and ETAtable are in separate workbooks.
The ETAtable is populated from the DBtable, via power query, to filtering out all rows that have dates. The user refreshes the ETAtable at the beginning of each use leaving only rows that need the date entered into the ETA column.
Unique ID is the unique Identifier
The goal is once the user enters Dates, in the ETA column(ETA table), they will click a button and a macro will transfer the dates, using the Unique ID to match the right row, from the ETAtable to the DBtable without changing any other rows.

ETAtable example has two dates entered by the user to be transferred to the DB table.
