How to merge content of 3 instances into Single Instance

[akash251998]

I have installed alfresco at three locations. Now I wanted to merge all three location data into 1 single instance. Is there any possibility to achieve this.

Or we can move the content of sites(folders) from one server to another server.

There could be two ways, 

1- Freeze any changes to the two servers and migrate all contents/sites to a single server.

a- You can do it using bulk export and bulk import

b- You can also use acp based export and import site/content tool.

Upto 5.1 , maywork for 5.2 as well: https://github.com/abhinavmishra14/alfresco-share-import-export/tree/master

Upgraded to SDK 4.1: https://github.com/abhinavmishra14/alfresco-share-import-export/tree/sdk4.1

c- You can also use this script:

2- Make use of replication, once all three servers are in sync, close down the 2 you don't want.
