I moved a library block from one library to another and I want the blocks in my model to reference the new library before I delete the old one. I have tried to iteratively change the parameter of 'ReferenceBlock', however, when I run the code below the reference doesn't change and still reads as OldLib and when I check with Go To Library Block.

My old library was in another project, referenced by my main project and the new library is located in my main project. Does anyone know what's wrong?

model = 'System';
oldlink = 'OldLib/Filter';
newlink = 'NewLib/Filter';
load_system(model);
blocks = find_system('System', 'ReferenceBlock', oldlink);
for blockIdx = 1:size(blocks, 1)
    set_param(blocks{blockIdx}), 'ReferenceBlock', newlink)
    disp(get_param(blocks{blockIdx}, 'ReferenceBlock'))
end

I managed to solve the problem. The code works fine. The issue was the block in the new library was linking to the old library. To stop the new library block referencing the old library block, I disabled the link on the new library block and then broke it.
