Please try to describe better what you are trying to accomplish. As Michael indicates, the attached screentshot does not seem to be connected to the problem on hand. fwiw - I find screeenshots terrible in general, vastly inferior to just some text copy & paste.
Is this perhaps a question in the process of moving multiple tasks from a lower (DEV) environment to the next (QA or PROD) and needed different on the targets? Or cloning tasks with with different schemas in the same DB?
Anyway the default target schema has a unique name in the exported task JSON and can be changed by any editing tool (powershell, perl, python, sed, awk,....) without extensive parsing. Just look for default_schema nd probably also control_schema and replace the quoted string after the colon on that line. See sample JSON snippet. Your choice whether to do this task by task or whether you can do an export 'all' and replace the those lines for all tasks in the export. Of course this is how it works today, and Qlik has the right to change the syntax in the future in which case you need to change the script but that's very unlikely.
Export, edit, Import! - With a bit more programming you can do it all 'in the air' using the the Enterprise Manager API's and those JSON's never need to touch the directories, just string streams in memory.
Hein.
