9. `vmctl` supports `--vm-native-disable-http-keep-alive` to allow `vmctl` to use non-persistent HTTP connections to avoid
error `use of closed network connection` when run a longer export.
10. Migrating data with overlapping time range for destination data can produce duplicates series at destination.
To avoid duplicates on the destination set `-dedup.minScrapeInterval=1ms` for `vmselect` and `vmstorage`.
This will instruct `vmselect` and `vmstorage` to ignore duplicates with match timestamps.
In this mode `vmctl` acts as a proxy between two VM instances, where time series filtering is done by "source" (`src`)
and processing is done by "destination" (`dst`). So no extra memory or CPU resources required on `vmctl` side. Only
