DataFlow Managed by Power BI - Move to Explicit Data Lake

Hi, 

We are starting our journey with Power BI and have the following concern: If we start using dataflows fully managed by Power BI, will it be possible to migrate the data lake later to a customer managed data lake? 

More info: 

Customer wants to start small, so starting with dataflows managed within Power BI makes sense. But, the limitation that the data lake can only be accessed within Power BI might become a limitation later in the process. 

So, in time, if we need to query the data lake populated by the dataflow with another tool, will it be possible to change the data lake subscription somehow to bring it to a customer managed data lake (Azure Data Lake Storage Gen2)?

If I need to move data from option 1 to option 2, will I have to re-create all reports attached to this data lake? 

Thanks
