Moving a test migration to production

-

i know if tell me if theory of mine safe implement:

project: migrate ad, dns , ca roles sbs2011 server 2012r2 standard , decommission sbs2011. both servers vms running on vmware.

i have cloned sbs2011 server , created 2012r2 standard server , placed them on separate, test vlan. wrote plan migration , proceeded migrate roles 2012r2 standard. after migrating moved 1 of or  windows 10 vm client machines test vlan , cloned 2 of our linux servers use cas sbs2011 box , moved them test vlan.

the migration being considered successful because client machine can reach ad/dns , linux server able obtain ca info. 

now theory is:

since test success, instead of re-creating 2012r2 server , doing migration after hours, can take test 2012r2 server transfer , fsmo roles source device (sbs2011) while still in test vlan, shut down, move production vlan, boot up, add domain, remove ca role sbs2011 vm , transfer fsmo roles 2012r2 (destination)?

the issues see if ad passwords changed between dates , if ca certs expire or renew between , (we have confirmed there no certs expiring or renewing).

i should mention test migration completed on feb 10th , migration take place after hours on 26th.

hi,

thanks post.

under normal conditions, transfer fsmo roles original server. should metadata cleanup on sbs 2011 and remove stale entries on 2012 r2 dc , delete stale entries dns. it’s hard since roles , features established on new server , can no longer considered new installed server.

in order minimize risk, better re-create new server , perform migration.

best regards,

alvin wang
