How do we migrate the OWB mapping from one server to another server?

Question

Here is my situation.
Source server
================
Project name : SOURCEOWB
Under this project, we have two module(MBTSOURCE, MBTTARGET).
In connection explorer, the locations are DW_MBT_SR, DW_MBT_TR.
We have 15 mappings on this project.
Source schema name is TXMBT_DW.
Target schema name is MBTTX_DW.
I want to migrate the whole thing to new server.
Here are the info about target location. After migrating to new server, i need to rename
as below.
Project name : CA_SOURCEOWB
Under this project, we have two module(CA_MBTSOURCE, CA_MBTTARGET).
In connection explorer, the locations are CA_DW_MBT_SR, CA_DW_MBT_TR.
Source schema name is CA_TXMBT_DW
Target schema name is CA_MBTTX_DW
Here are my steps i followed.
===============================
1. Created the source and target schemas in new machine.
2. Create a new workspace
3. Export the mapping with dependent objects from source server and imported in new server.
4. changed the source and target location successfully.
5. Renamed the project namd, module names as i needed successfully.
But only issue is, i am not table to change the location name.
Again, i tried the below steps.
1. uninstall the workspace and create the workspace
2. create source and target locations as i needed(CA_DW_MBT_SR,CA_DW_MBT_TR).
3. import only mapping
4. Able to register the mapping
Here i am not able to configure the module for newly created locations.
I right clicked on module and click Configure, go to Stream Administrator and not able to find
the source and target locations over there.....
How do we resolve this?
My data warehouse is runing for each state. I want to copy one state mapping and import into
another state and customize the mapping. I have hard time to change the location name. Because,
location name has state code. I can not use the same location name for all other state.
Any help is highly appreciated.

Hello Oleg, Thanks for your input.. It helps... but the problem is not completly solved.
let me explain my whole steps. Plesae review and let me know if i missed anything.
1. Created new workspace. the workspace is successfully created.
2. Login to new workspace.
3. Go to Locations, create source location(entered host name,username, password etc)
4. Created target location(entered host name,username, password etc), go to db connector on target location, created new db connector and linked the source location here.
5. Exported mapping and import into new workspace.(I can not use the location name in the exported workspace).
6. Renamed the project name, module name as i needed.
7. Double click the module name under Oracle and changed the meta data location and data locations.
8. Right click on soure and target module and click configure, change the the location and streams administrator.
9. Right click on mapping and go to configure, go to table operators and change the location as i need.
10.Right click on target module(under oracle), click generate. On this step, i get the below error
VLD-1141: Internal error during mapping generation.
Java.lang.ArrayIndexOutOfBoundsExeception
11. Go to control center, register the source and targert and followed the step 10. I get the same error.
I am almost close to complete this task. But i got stuck in the last step.
