Hi Hasan, You can try to add additional 2 new CAS/HUB servers to the WNLB, after that, please remove the old 2 ones. Frank Wang TechNet Community Support

Hi, 1) Shutdown Old Servers... Reset the Account from AD... 2) Install 2 fresh servers with same O/s,Patches,Name and Network Configuration 3) run setup.com /m:recoverserver Reason is that it will recover all your existing Settings for owa url,certificates connector setting etc.....
