After copying space: references to lucidcharts lost in new space

[Nils Leger]

Hello,

in my company we have an internal and an external confluence instance. Every night, we copy one of our spaces from the internal to the external instance via the Confluence CLI. This space to be copied also includes some pages with lucidcharts. A lucidchart is always stored as a .json-file and attached to the page. Therefore, it has an unique id. This id is stored in the page content: 

<ac:parameter ac:name="attachmentId">24916583</ac:parameter>

Problem: After copying the desired space into the external instance, the lucidcharts aren't displayed there.

Reason: As the .json-File is uploaded, Confluence assigns a new attachment-id which doesn't match the one in the page content.

Can you think of any not-dirty solution for this problem? 

Thank you in advance and best regards,

Nils
