Importing old sensor data from another platform

Hi there.
Sorry if this is a stupid question but I am old time domoticz user with 70+ devices and sensors currently in the process of migrating over to HA.
I have moved over most of my switches/ lights / remotes to HA now but am in two minds over my sensors.

I have several years worth of multiple weather sensors and power sensor data available on domoticz (which I can export )
Now I can take the easy way and leave the domoticz installation running purely for the sensors or migrate them over
However I would need to also import the old / historical data into the new setup so that the sensor data is available seamlessly and I am unsure if it is possible at all.

Any thoughts or suggestions?
