MetaFrame 1.8 Server Migration to MPS

The migration process from MetaFrame 1.8 to MPS 3.0 requires the completion of certain steps to ensure that the environment continues to run properly. Because of the architectural changes evident between MF 1.8 and MPS, it is imperative that the farm be placed in "interoperability" mode, which basically means that the server farm is backward compatible. This allows MF 1.8 and MPS servers to coexist and serve users. Interoperability mode, however, is temporary, and Citrix strongly recommends that this be a transitional phase. After the last MF 1.8 server has been migrated , the farm should be placed in Native mode so that you can take full advantage of all the new features and technologies of MPS.

Here are the steps required to complete a migration from MF 1.8 to MPS 3.0:

1.	If you plan to use a dedicated database server for your IMA Data Store, make sure your database is ready.
2.	Install and configure your Citrix License server.
3.	Upgrade an existing MF 1.8 server that is not the current Master ICA Browser. This step is very important; otherwise , all sorts of problems will occur in your environment.
4.	During the installation of the first MPS server, give your new server farm the same name as your existing one.
5.	After the installation is complete and the server is restarted, this upgraded server automatically becomes the new Master ICA Browser.
6.	Place your new server farm in interoperability mode by launching the Management Console, right-clicking the Farm node, and selecting Properties. Now select Interoperability on the left and check the box next to Work with MetaFrame 1.8 Servers in the Farm (see Figure 5.6). Figure 5.6. Remove the server farm from interoperability mode.
7.	Begin migrating existing MF 1.8 servers and make sure that during installation you choose Join an Existing Farm.
8.	After the last MF 1.8 server has been migrated and there is no need for the farm to remain in interoperability mode, launch the Management Console, right-click the Farm node on the left, and click Properties. Select Interoperability and uncheck the box next to Work with MetaFrame 1.8 Servers in the Farm so the screen looks like Figure 5.6.
