Combining old Enphase data with new

When Enphase stopped working a while ago I resolved to a HACS integration. Enphase (DEV). That resulted in two sets of solar panel data.

The sensor data from the original integration is still there and I use it to get an estimate over a longer period. (monthly, yearly, etc.)

Now the original Enphase is fixed I want to return to that integration without losing my sensor data from June, July and August. Is there a way I can add the DEV data to the old data?

See the answer I gave in another post on this forum.
