How to join alfresco 2.1+3.0+3.2

[golden_eye]

Hello
i have a next problem.We are using  3 different versions of alfresco.Alfresco 2.1,Stable labs 3.0 and 3.2.
The problem is that in each of  version are the documents that are relevant and should not be lost.
My question know is how can I join all 3 alf_data folders into one mysql database.
Is this even possible and how should begin with it?
If i try with import/export of acp isn't possible between version.Is that right?
Some debate on this issue,please?

Tnx.

In order to use export/import, you'd need to upgrade the v2.1 and v3.0 servers to v3.2 first.

Ok clear for import/export.
But i' am having trouble upgrading.Some advise on this?
We have on 3.0 our production and we want to move on 3.2.I made the copy of extension folder,alf_data,WEB-INF/lib on production.Then i install new 3.2.
So on everything is ok.I start ALfresco 3.2.I enable Ldap and CIFS access.ALl this is working fine,main reason why we wont move on 3.2.
But then mess start.
I stop alfresco 3.2.copy sql from production to database alfresco 3.2.
I start server again.I can see Index recovery started: 1.762 transactions
Index recovery completed.Reindex  100% complete
[org.alfresco.repo.admin.ConfigurationChecker] The Alfresco root data directory ('dir.root') is: /opt/Alfresco/Alfresco-3.2/alf_data

How to solve this error?Alfresco crash.
Please.
I follow the steps written about upgrade on http://wiki.alfresco.com/wiki/General_Upgrade_Process.

You need to copy your database AND your content,  you can't do one without the other.   From what you have said you just copied the database, hence the problem.   

Or as Mike said once you have upgraded your old versions use Export from what used to be the old version and import into your new instance.

Hi i figure it out the issue with workflows,but now i have another questions.
I don't wanna use any more some workflows.
I delete it in extension folder and in web-client-config-custom.xml.
My question here is they will be also deleted from database.Because when i will upgrade database and alf_data from 3.0 to 3.2 this probably would't work.Or should?
How to delete non using workflow in database.Will server automaticlly recognized the new configuration or i need to by hand delete it from database?
How to make it consistent, that upgrade will succeed?
