ADFS works on host name, so changing IP will not impact the upgrade or any function. 

Thanks Sathosh for the quick update.


Also , i could see the limitation of RP Trust on should be less than 99 and FS servers should be less than 5 in a farm with WID database.

4 FS & 4 WAP and 90+ RP's , can we upgrade it to 4.0 with out any issue ?

or we face any database issue on this ?

How many trust can be used practically ?





Hi Renga,


Since you have 90+ RPs which is approx. upper limit for WID Database RP support. I would suggest you to migrate WID to SQL database first. else it could create performance issue and trouble in scalability.


I believe you will use add and replace method while upgrade. (MS Note: Before you can move to AD FS in Windows Server 2019 FBL, you must remove all of the Windows Server 2016 or 2012 R2 nodes. You cannot just upgrade a Windows Server 2016 or 2012 R2 OS to Windows Server 2019 and have it become a 2019 node. You will need to remove it and replace it with a new 2019 node.)

Truly speaking I have not used this much RPs. You can take the help to below URL to calculate Server requirement.


Hope it will help you.
