Do i need to move system databases?

Currently i have sql server 2008 R2 and i am planning to move to SQL SERVER 2014.

I am planning to do side by side upgrade.

so,

Steps 1:

i made a full backup of user databases on 2008R2, and restored on 2014.

Scripted out Jobs,alerts, operators, and crated on 2014

transfer logins using SP_Help_rev-login (msdn) to 2014

Created database mail, linked servers, Triggers on 2014.

Configured Replication(push- transnational ) on 2014 same as on 2008 R2(X)  ( from server X--Y  and X--Z )

my questions are : 

1.do i still need to backup master and msdb on 2008 R2  and restore on 2014?

2.also i have distributor database on 2008R2(X) , do i have to move the from 2008R2 to 2014?

please let me know 

Thanks in advance
