Please follow the following steps


At the exsiting server:- 
    Disable indexing in the present system, stop and start stop, 
    Take backup of Alfresco installation DIR
    Take backup of DB

At the new server :- 
   Restore the DB
   Install the new alfresco installation (imp:-do not start the service) 
   copy the alf_dir of the old instance  directory to the new inststallation directory (Please copy only 2 directory named "contentstore"  and  "contentstore.deleted") (Do not copy other directory)
   start the new alfresco instance 
   You have now upgraded the instance without indexing 
   enable indexing at alfresc-global.properties 
  restart the service 
   You have a upgraded system with solr indexing enabled

I think you want to have two different tasks.
First Upgrading then migration.
Do you want to migrate all the customization and content in to the new system?

In Upgradation you will deploy all the customization in to the new server and make sure everything is working properly.
Then you will have to transfer all your contents by migrating your alf_store and database

thnx for the answer but i have some additional questions:

1. when u say "restore the db" u mean dont touch the generated postgres folder in dir.root (c:/alfresco/alf_data/postgres) and use the vendors database tool to restore the exported "alfresco.backup" file from the old server?

2. i recognized that in the database there are some entries pointed to the old server IP. will this have some side effects?

3. (sorry for that) how do i stop the indexing? (u mean by editing an entry within the alfresco-global.properties file)

4. can u tell me about what happens when i use new generated passwords for the database and keystore at the new installed server?

1> Yes, you need to restore from the previous instance of Database backup
2> This, my experience says that(you have to cross check) they IP address entry is in the "alfresco-global.properties"
3> In "alfresco-4.2.c/tomcat/shared/classes/alfresco-global.properties" there is section


### Solr indexing ###
index.subsystem.name=solr
dir.keystore=${dir.root}/keystore
solr.port.ssl=8443
‍‍‍‍‍‍


### Solr indexing ###
index.subsystem.name=noindexing
#dir.keystore=${dir.root}/keystore
#solr.port.ssl=8443
‍‍‍‍‍‍

4> Nothing happens when you use new gerenated password(I am not sure about this, take other advice also), I normally keep the same password

thnx helpded me a lot.. so thumbs up for ur comments ;O)

dunno if it is important.. but i read that its important to copy the models to the solr folder.

from the old server location (dir.root/solr/archive-SpaceStore/alfrescoModels) to the new server location (dir.root/solr/archive-SpacesStore/alfrescoModels)

and old location on server (dir.root/solr/workspace-SpacesStore/alfrescoModels) to new location on server (dir.root/solr/workspace-SpacesStore/alfrescoModels)

Not sure about dir.root/solr/archive-SpaceStore/alfrescoModels, I have to come across it.
Did you copy it also
