How to keep SID when using "replace_block"?

I work with MATLAB R2016b and I cannot make use of keeping the SID when replacing blocks.

I have an old project where we copy the partial models from one model to another with "replace_block".

However, using the 'KeepSID' option, the SID Number will be reset when the "replace_block" is applied.

This option is still available but not documented well. You can keep the SID using the following commands:

>> open_system('vdp');

>> get_param('vdp/Mu','BlockType')

ans =

  'Gain'

>> simulinkID = Simulink.ID.getSID('vdp/Mu')

simulinkID =

  'vdp:4'

>> blk = sprintf('simulink/Math\nOperations/Bias');

>> replace_block('vdp','Name','Mu',blk,'KeepSID');

>> get_param('vdp/Mu','BlockType')

ans =

  'Bias'

>> simulinkID = Simulink.ID.getSID('vdp/Mu')

simulinkID =

  'vdp:4'
