When migrating flows stored in a local directory that contains subflows the import will fail. Flat flows import as expected.
There is a message that says "Migration completed with errors, The following flows were not able to be migrated". The flow referenced will be a subflow contained inside the flow we are trying to import which suggests an issue when these are being unpacked.
Cause
Not enough memory on the ARD HUB.
Environment
ARD Client Version - 3.0.000.11

Increased the java heap space for the ARD HUB, this is a recurring problem for windows deployments of the HUB when it is not set high enough during installation. We recommend 4 GB the customer had something like 250 MB
