I have 2 servers
Server1 – Windows 2012, Domain controller, Exchange 2013 Cu7
Server2 – Windows 2012, Domain controller
I need to upgrade Acive Directory and Exchange to 2019.
Plan is to install new Exchange 2016 (migrate from 2013 Cu7 to 2016). Remove 2013, updat domain controllers from 2012 to 2019 and then upgrade Exchange 2019 (I can't migrate directly from Exchange 2013 to 2019 because Exchange 2019 doesn't support 2012 domain controllers, but 2012 R2).
To install Exchange 2016 I need updatge EXchange CU7 to CU23. Unfortunately, it turned out that I cannot install CU23 on CU7 directly. I need to install first CU20 then Cu22 and then Cu23 (because of .Net)
Unfortunately the download links for Exchange 2013 Cu20 and CU22 are not working.
All 2013 versions
Is it possible to make Exchange 2013 CU20 and CU 22 available again somewhere?
Can anyone help me with this?
