Cost Loaded 6k activity Project Overhaul

adding the new ativities is easy the hard part is the revision of the existing relationships.

The very first thing to do is to open the original project and select send project and email this project to yourself.

Next open the revised project and select send project and email this project to yourself.

Now is something goes wrong you have a clean starting point again.

I always do this prior to making and MAJOR revisions and it has saved me tons of works in the past. 

I would do the following but I would certainly spot check it throughly after it was done.

export the revised schedule as an xer

Open the original schedule 

select file import and select the revised xer file and then select add to existing

during the importing process when you get to the update project options 

in the 1st section under Data Type: Activity select update existing

in the 2nd section under Data Type Global: select update existing for everything

in the 3rd section under Data Type Project: select update existing  except for the wbs select insert new

try that but check it aftewards

Zoltan I have tried that in the 2nd section you have mentioned. I have seen primavera had maintained previous relationship. So when I imported xer file I see both old & new relationship. My solution is about this issue before import xer file scheduler have to remove all relationship.
