+><P
+>In the IT world there is often a saying that all problems are encountered because of
+poor planning. The corrollary to this saying is that not all problems can be anticpated
+and planned for. Then again, good planning will anticpate most show stopper type situations.</P

+>Those wishing to migrate from MS Windows NT4 domain control to a Samba-3 domain control
+environment would do well to develop a detailed migration plan. So here are a few pointers to
+help migration get under way.</P

+><P
+>The key objective for most organisations will be to make the migration from MS Windows NT4
+to Samba-3 domain control as painless as possible. One of the challenges you may experience
+in your migration process may well be one of convincing management that the new environment
+should remain in place. Many who have introduced open source technologies have experienced
+pressure to return to a Microsoft based platform solution at the first sign of trouble. </P
+><P
+>It is strongly advised that before attempting a migration to a Samba-3 controlled network
+that every possible effort be made to gain all-round commitment to the change. Firstly, you
+should know precisely <SPAN
+CLASS="emphasis"
+><I
+CLASS="EMPHASIS"
+>why</I
+></SPAN
+> the change is important for the organisation.
+Possible motivations to make a change include:</P

+><P
+>It is vital that oit be well recognised that Samba-3 is NOT MS Windows NT4. Samba-3 offers
+an alternative solution that is both different from MS Windows NT4 and that offers some
+advantages compared with it. It should also be recognised that Samba-3 lacks many of the
+features that Microsoft has promoted as core values in migration from MS Windows NT4 to
+MS Windows 2000 and beyond (with or without Active Directory services).</P

+>This is not a definitive ste-by-step process yet - just a place holder so the info
+is not lost.
+
+1. You will have an NT4 PDC that has the users, groups, policies and profiles to be migrated
+
+2. Samba-3 set up as a DC with netlogon share, profile share, etc.
+
+3. Process:
+ a. Create a BDC account for the samba server using NT Server Manager
+ - Samba must NOT be running
+
+ b. rpcclient NT4PDC -U Administrator%passwd
+ lsaquery
+
+ Note the SID returned by step b.
+
+ c. net getsid -S NT4PDC -w DOMNAME -U Administrator%passwd
+
+ Note the SID in step c.
+
+ d. net getlocalsid
+
+ Note the SID, now check that all three SIDS reported are the same!
+
+ e. net rpc join -S NT4PDC -w DOMNAME -U Administrator%passwd
+
+ f. net rpc vampire -S NT4PDC -U administrator%passwd
+
+ g. pdbedit -l
+
+ Note - did the users migrate?
+
+ h. initGrps.sh DOMNAME
+
+ i. smbgroupedit -v
+
+ Now check that all groups are recognised
+
+ j. net rpc campire -S NT4PDC -U administrator%passwd
+
+ k. pdbedit -lv
+
+ Note - check that all group membership has been migrated.
+
+
+Now it is time to migrate all the profiles, then migrate all policy files.
+
+Moe later.</P
