Merging source in SVN

My team has used Primefaces for our projects. We sometimes have several branches of the projects with a new Primefaces's release. For example, we currently have a project with two branches, a branch for using Primeface 4.0, a trunk for using Primeface 5.0, and we are working these parallel branches. Our project looks like the following:

- myProject
 - branches
     + primefaces4
 + tag
 + trunk (primefaces5)

My problem is how to copy the same source from the trunk to the branch "primefaces4". That is where SVN Merging can help!

Here is the steps those I have conducted in my project.

Step 1: open the project with the branch "primefaces4"

Step 2: Team > Merge... Chose the trunk's URL.
For example: http://192.168.9.10/svn/myProject/trunk

Step 3: Select the revision from "trunk" to merge.
For example:

 +--revision--+--date--------+--author----+--comment---+

 +  10        + 03.10.2014   + vanhuong   + f1: part 3 +

 +  9         + 03.10.2014   + ACB        + f2: part 2 +

 +  8         + 02.10.2014   + ACB        + f2: part 1 +

 +  7         + 01.10.2014   + vanhuong   + f1: part 2 +

 +  6         + 01.10.2014   + M2M        + f0: part 3 +

 +------------+--------------+------------+------------+

In my case, I have two times for merging. The first chosen revision is "7".

Step 4: Click "Merge". You code is merged from trunk with revision from "6" to "7".

Step 5: Update code and resolve conflict (if needed)

Step 6: Back to Step 3 with the revision "10".
