Migration SBS 2008 -> 1st S2012R2+Exchange and 2nd S2012R2 DC

hello,

i have problem migration sbs 2008 s2k12 std r2.
in our company have 1 server sbs 2008 standard.

now time, go server 2012 r2 dc , second server s2012r2 exchange 2013.

on new hardware install s2012 , addeed hyper-v role.
in hyper-v created 2 server s-mail , s-dc.

because want test procedure, create snapshot of physical server via disk2vhd , create vhdx file this.

now, have server 2012 r2 3 machines in hyper-v (sbs virtual copy, s-mail , s-dc).

on virtual sbs run adprep /forestprep , domain prep install dvd of 2k12 server. no problem this.

after added s-dc , s-mail domain.local.

on s-dc server, install ad domain service role , promoted server domain controller settings:
dns + gc, default-first-site-name, got warning "a delegation dns srever cannot created, because te autoritative parent zone cannot found."

after install, config , reboot s-dc, looking in ad , there in domain controllers folder, found sbs virtual , s-dc domain controllers.

next install s-mail, migrate data prom exchange 2007 sbs exchange 2013 on s-mail. there no problem, after uninstall exchange 2007 sbs server.

after create backup of dhcp on sbs server, remove role , restore backup on s-dc server. no problem this.

now, wrote "netdom query fsmo" 

schema master .... sbs

domain naming master .... sbs

pdr ..... sbs

pid ... sbs

infrastructure .... sbs

i started move role s-dc. open ad users , computers, there in operation master moved pdc, infrastructure , pid.

in ad domain , trust moved operation master.

after run "regsvr32 schmmgmt.dll" , in mmc -> schema ad changed operation master new s-dc.

after run netdomquery fsmo , 5 roles, on s-dc.

now, domain doest work without sbs server turned on. when sbs server not turned on, no clicent cant access anywhere, on s-dc cannot open ad users , computers, etc.

when boot sbs server, domain work right. 

so, think - last step run dc promo on sbs , demote it. there problem - this:

dont checked "this last dc , delete domain". dont select this.

after next, got - cant find other domain controller.

in next step select "delete delegation dns server".

when proces stard, got after few seconds this:

a domain controller not contacted domain domain.local contained account computer. make computer member of workgroup rejoin domain before retrying promotion.

i checked things , setting, don´t know, or problem / error.

thanks re, john
