I did this option when upgrading my OS. However, there were quite a few gremlins that we had to ferret out, mostly around Certs, and connections between the old primary and the secondaries, etc. Took a couple of weeks to find them all.

There is a third and usually better option here: backup and restore. No migration needed, restore on update OS, tests your recovery procedures, clients and all site systems untouched, no “interim” periods, and lots more.

Personally I am in the middle of a side0by-side migration from 1602 to 1602 just because my old primary site is on 2008R2.

We were on a similar boat; Initially single Primary Site Server on WS 2008 R2 with ConfigMgr 2012 R2 CU3 1. Upgraded in place to ConfigMgr 1511 a. Our plan was to upgrade that to 1602 but for some reason no matter what we did it never showed up on the console 2. Built new WS 2012 R2 with ConfigMgr 1511 > upgraded to 1602 3. Migrated pretty much everything from old server to new server (1511 to 1602 migration) 4. Had issues with DPs and we still seem to be having some weird cryptic issues a. Application Deployments with following errors: “CI Version Info timed out” or “CI documents download timed out” b. Site server deploys client to itself but it never reports to the actual site c. Errors showing in Site Status for Application Catalog web service point and Application Catalog website point but no relevant errors in logs If I could do it again I would bring up a new server without migrating anything and configuring it from scratch. We are small enough that we can actually do this but didn’t expect these many issues from a migration. You should note as well you can’t “install 1602” from scratch. You must install 1511 first and upgrade to it.

Hi, So 1 vote for in-place upgrade of OS followed by in-place upgrade of SCCM Would anyone 1) Build a new server with W2K12R2, install SCCM R2 CU3, restore DB and Data from backup of old server, in-place upgrade SCCM to 1602. 2) Build a new server with W2K12R2, install SCCM 1602, manuel "rebuilt" configuration. Perhaps restore selected data from backup. 3) Build a new server with W2K12R2, install SCCM 1602, start from scratch with a new configuration, applications and TS. How will my clients reacts to all this? rg Richard 12. maj 2016, 20:24:07, you wrote: > I'm never a fan of in-place upgrading an OS, especially on a server. > Having said that I'd do an R revision in-place then upgrade CM in-place. > -----Original Message----- > From: [email protected]<mailto:[email protected]> > [mailto:[email protected]] On Behalf Of Richard > Bjerregaard > Sent: Wednesday, May 11, 2016 5:10 PM > To: [email protected]<mailto:[email protected]> > Subject: [mssms] Best upgrade path ? > Hi everyone > Looking for some guidance, high level steps. > Have > SCCM 2012 R2 CU3 running on Windows Server 2012 RTM > 4.500 clients, all windows 7, ~200 applications. > Just 1 server.
