Each Domain Controller.

Also note that you asked if "Can I be able to synchronize the current AD 
user credentials with
FreeIPA 2.2 or do I have to upgrade to FreeIPA 3.0"

You cannot synchronize already existing passwords with IPA 2.x.  You 
would have to force AD users to change their passwords in order to get 
the clear text password to send to IPA.

and
https://fedorahosted.org/389/ticket/355

The problem is caused when you have a user ID in IPA that has the same 
user ID as a user in AD, but you didn't want them to be synced, and the 
AD user entry is outside the scope of the windows sync agreement.  This 
may or may not be a problem in your deployment.

See above.
>      b) If some users have a smartphone to exchange setup the winsync agreement sees that as the user having 2 ous's and first adds and then deletes those users......oops.....I lost 20% of my users that way....
Is there a ticket/bz for this issue, or is this the same issue as above?

There are workarounds.

You can also use db2ldif to get around the 2000 user limit mentioned above.
