Hi All
I am facing issue with code compare between two org
for Example
in Dev_Org: I have pages and classes with custom lables and all developed components will be moving to Package_Org (Where I have created Namespace for managed package to publish into SF app exchange)

my Issue here is I have implemented hundreds of classes and pages. my developers concurrently working in Dev_Org and I should move this changes to Package_Org, I am using eclipse for deployment, but before deployment I always compare code between two org. and what ever the necessary changes I will deploy into another org. I am facing issue with nameSpace prefix. because take  page-1 I have used custom lables in it. and initially i deployed code to Package_Org. but in next deployment I have to move to page-2 but I should consider other changes for this purpose I am comparing code here if you observe I dont have any changes in page-1 right. but in code compare I got page-1 in the code difference list, due to namespace prefix appended in package_org.

Eg.,

page-1 in Dev_org
<apex:page>
     {!Label.HellowMessage}
<apex:page>
page-1 in Package_Org
<apex:page>
     {!Label.Namespace__HellowMessage}
<apex:page>
But like this happens for all the pages. I should really inspect each and every page unnecessarely wihout having code changes in it. what should I do. also I found some of the cusom labels dont have prefixed with nameSpance for them, why?
Eg.,
page-1 in Dev_org
<apex:page>
     {!Label.HellowMessage}
     {!Label.goodMorning}
<apex:page>
page-1 in Package_Org
<apex:page>
     {!Label.Namespace__HellowMessage}
     {!Label.goodMorning}  -  (why this custom lable dont have prefix)
<apex:page>
