Domain Migration

I have a plan for a domain migration and would just like to know if you men and women would like to have a quick look over it and see if I've missed anything that may cause issues. I only have tonight to complete the migration.

1) Network 1 - domain company1.local - ip range 192.168.11.x - 15 users - sage accounts, 2 programs which use SQL databases. 2 servers, both DC's

2) Network 2 - domain parentcompany.local - ip range 192.168.1.x - 150 users - sage accounts, 2 programs which use SQL databases, various other packages - 12 servers.

both are currently linked together using a trust and are held together using a VPN tunnel through 2 draytek 2830N routers.

Both servers and networks can see each other with no issues.

My Intention:
Get rid of company1.local and merge all users and servers into parentcompany.local

My Plan:

1) Install ADMT
2) create local administrator accounts on all 15 machines at company 1
3) Make local admin accounts on all databases
4) run ADMt and migrate all users and SIDs from company1.local to parentcompany.local
5) join all 15 machines to parentcompany.local using profwiz (https://www.forensit.com/uk/downloads.html)
6) dcpromo both servers
7) join them both 2 new domain - 1 as a DC
8) Reshare shared folders/printers etc
9) setup programs to connect to SQL DB using new logons
10) remap sage drives

If there is anythign you think I have missed or should be doing please let me know.

Thanks for any advice.
