Hi,
Here are the steps to transfer the Objects(Standard/Custom), Classes, Pages, Tabs, etc from one Salesforce organization to another with having different users.
1. Open Force.com IDE and create a new Project from source org.
2. While creating project select the components you want to transfer manually.
3. After completion, select either one object/Class/Page or as many you want ;
4. Then right click on it –> select Force.com IDE –> Deploy to Server;
5. Enter the login details for Destination org along with Security token
6. Then Select Archive Option where you want to store ZIP file for the selected Items to be Archived –> click Next;
7. On deployment plan page, Click Next
8. If you get “Success” as result then click on Finish button and thus you will be success in transferring the Objects/Classes/Pages etc from one Org to other, but if you get an Error message then try to remove that errors and try again the above mentioned steps.
Thanx.
