Thanks @cstns appreciate quick feedback.

Hoping to also get the "OK" from @joepavitt and perhaps @sumitshinde-84 too since it arose from confusion in the new pipelines article here: FlowFuse/website#2603 (comment)

[joepavitt]

First one states that keys will transfer, but the values will not. Now, the new one states that keys will not be overwritten, but that implies the values will?

@Steve-Mcl just chasing for a reply to my comment above

Now, the new one states that keys will not be overwritten, but that implies the values will?

Thats not what i (and the other guys who discussed this on Slack) infer from it ;) but since you did, perhaps a simplification would be better?

Environment variables in the target instance that already have a value will not be overwritten

Clean, to the point.

More explicit?:

Environment variables will be copied to the target instance but any that already have a value will not be overwritten.

Super precise?:

Environment Variables will be copied from the source to the target instance. Any Environment Variables that the target already has will not be overwritten if they contain a value however empty Environment Variables will be updated.

Thoughts?

This please
