Merge SRM Organizational Plan to HR ALE

Hi experts

Does anybody of you have documentation about how to merge an existing SRM Organizational Plan (actually maintained manually / locally in SRM) to HR ALE?

What can we do if there are conflicts with number ranges?

Alternatively, does anyone know how to ALE from SRM testsystem to SRM productive system?

Can you recommend using ALE or are there to many problems?

Thanks for your help.

Best regards,

Corinne
