TM1 Forum

Hello,

Let's say you have two TM1 Servers, server A and B. You built a book design on PAW for server A and wants to migrate it to server B (suppose both share the same structure (cube names, views, dimension names, processes, and whatelse you have in your book), unfortunately the 'migrate assets' feature on PAW only works if both servers share the same name, so you can move from DEV server to PROD server but if you want to migrate to Server A to server B, you can't since it will keep looking for the Server A's objects (cubes, dimensions, etc).

I've found a way on how to migrate between different servers. You'll need a linux machine because of the paw migration export file is in the .gz format, I tried using windows and it didn't work, PAW couldn't detect the file on import, if anyone knows how to do it on windows then please post here.

1. Go go PAW > Administration > Lifecycle Management > Create Snapshot > Select the books that you want to migrate to Server B > Add to cart > click on "Export".
It will download a your-name.gz file on your computer.

2. Open your linux terminal and go to the download folder, unzip it with the command 'sudo gunzip your-name.gz'

3. Open the unzipped your-name (no extension) file on your preferred text editor (I use VS Code).

4. Find the name of your server using CTRL+F. It will appear on a lot of lines like this: "serverName\":\"ServerA\", select the name of your server and use the replace text feature (ctrl+h) to replace "ServerA" with the name of the server you want to migrate, in my case it will become like this: "serverName\":\"ServerB\". Use the "Replace All" feature so all lines can be replaced.

5. Save the file, go back to the terminal window and zip the file again with the command 'sudo gzip your-name'

6. Go to PAW > Administration > Lifecycle Management > Manage Snapshopts > Click on the button "Import" in the bottom right, select the your-name.gz file (the one that you changed the server names), import it, and migrate it to your personal folder and then you can move it to the Shared Folder.

That's it, when you open the new book it will look for the same objects but in server B.

Thank you.

Can a mod move this to the 'Useful code, tips and tricks' section? Thanks.

Thank you for sharing.

While we're at it, can anyone explain why this

makes any sense?
From what I can see in my testing, you cannot overwrite the existing book, so you need to delete the target book first and then move the personal one you now have over the previous one. This causes the following:
* no bulk promotions (you're going book by book)
* you lose all security at this point on this book and need to reset it (from screenshots and what not?)
* not sure what happens with any links to the book from other books.

Is it just me being stupid and missing something very obvious or is LifeCycle manager promotion so manually intensive that it's 'easier' to re-implement the changes on the other side?

Thanks,
Y

Hi,

Isn't there also the option that when you Migrate and it errors (because the target server doesn't exist) it allows you to Select a TM1 database and you can then select the one you want?

This never happened to me before, I belive it's only for cloud clients no? On PAW local it doesn't let you select the target server or am I doing something wrong?

Hi,

You create the snapshot, go to lifecycle management Manage Snapshots,
Click Import, select the exported zip,
Select Migrate, Migrate Again

It should say Select Target Environment (there should be a default)

Enter a Folder name
Select Migrate again
If the server name doesn't exist it should fail, saying TM1 database not available
To the right of this message you should see in Red 'Select a TM1 database'
Select the one you want and Save

I've never seen this before. How do you create a snapshot of a database that doesnt exist thouogh? Like I made modifications on server A and want to migrate this to server B but both exist already. I could only replicate this by downloading a snapshot of an existing server doing what I did in my original post (download the file, change the name manually, zip again, etc) but changing the name to a server that doesn't exist, then it showed me this page asking to select the database...

Also I noticed that the buttons that executes processes didn't update to the new server that I selected... also losing its parameter configuration
When I do this manually, everything works.

Yeah it's annoying having to set up the security on each book manually again, but at least now you don't have to change the cube views, processes, etc inside the books manually anymore hehe. And if you keep all your books organized inside folders, it's easier to move one folder from your personal to the shared folder.

Good question!
I tried this now and in both cases, when you have a button navigating to another sheet inside the same book and when you have a button navigating to another book inside the same folder seemed to work though...

Hi,

Thanks for sharing this.

I have both databases ( Dev and Test) on the same server, one called FnP_Dev and the other one FnP_QA

I created all the books and views in DEV and now when I try thing Life Cycle Management to migrate them to QA, yes the package gets created and it gets migrated, but all the Views are still pointing to DEV Cubes

I have only one Workspace Server and there I have 2 databases setup.

And I cannot see how I can even change the Database name in the Views

WHen I go to setup SOurce to Target Mapping, on the Drop Down for Source I have Only "DEFAULT" and on the Drop Down for Target I also have only "DEFAULT"

Is there any way to change the Database Name after the Vews are migrated?
Thanks

Yeah, I had the same problem, that's why I had to export the image and change the "server-name" setting manually and then re-import the image to paw, like I mentioned in the opening post. Did you try that method?
