Installing on Windows
=====================

EDB provides a graphical interactive installer for Windows. You can
access it two ways:

-  Download the graphical installer from the `Downloads page <https://www.enterprisedb.com/software-downloads-postgres#migration-toolkit>`_  and invoke
   the installer directly. See :ref:`Installing directly <Installing directly>`  .

-  Use Stack Builder (with PostgreSQL) or StackBuilder Plus (with EDB
   Postgres Advanced Server) to download the EDB installer package and
   invoke the graphical installer. See :ref:`Using Stack Builder or StackBuilder Plus <Using Stack Builder or StackBuilder Plus>`  .

Prerequisites
-------------

You must have a Java JVM (version 1.8.0 or later) in place before Stack
Builder can perform a Migration Toolkit installation. `Adoptium <https://adoptium.net>`_ 
offers prebuilt OpenJDK binaries from fully open sources.

The Java executable must be in your search path (``%PATH%`` on Windows).
On Windows, use the following command to set the search path,
substituting the name of the directory that holds the Java executable
for ``javadir`` :

``SET PATH=javadir;%PATH%``

Installing directly
-------------------

After downloading the graphical installer, to start the installation
wizard, assume sufficient privileges (superuser or administrator) and
double-click the installer icon. If prompted, provide a password.

In some versions of Windows, to invoke the installer with Administrator
privileges, you need to right-click on the installer icon and select
**RunasAdministrator** from the context menu.

Proceed to the :ref:`Using the graphical installer <Using the graphical installer>`  section in this topic.

Using Stack Builder or StackBuilder Plus
----------------------------------------

If you are using PostgreSQL, you can invoke the graphical installer with
Stack Builder. See `Using Stack Builder <https://www.enterprisedb.com/docs/supported-open-source/postgresql/installer/03_using_stackbuilder/>`_  .

1. In Stack Builder, follow the prompts until you get to the module
   selection page.

On the Welcome page, use the drop-down listbox to select the target
server installation from the list of available servers. If your network
requires you to use a proxy server to access the internet, select
``Proxy servers`` and specify a server; if you do not need to use a
proxy server, click ``Next`` to proceed.

1. Expand the **Registration-requiredandtrialproducts** node.

2. Expand the **EnterpriseDBTools** node and select **MigrationToolkit**
   .

3. Proceed to :ref:`Using the graphical installer <Using the graphical installer>`  .

If you are using EDB Postgres Advanced Server, you can invoke the
graphical installer with StackBuilder Plus. See :ref:`Using StackBuilder Plus <Installing on Windows>`  .

1. In StackBuilder Plus, follow the prompts until you get to the module
   selection page.

On the Welcome page, use the drop-down listbox to select the target
server installation from the list of available servers. If your network
requires you to use a proxy server to access the internet, select
``Proxy servers`` and specify a server; if you do not need to use a
proxy server, click ``Next`` to proceed.

1. Expand the **Add-ons,tools,andutilities** node and select
   **EnterpriseDBMigrationToolkit** .

2. Proceed to :ref:`Using the graphical installer <Using the graphical installer>`  .

Using the graphical installer
-----------------------------

1. Select the installation language and select **OK** .

2. On the Setup Migration Toolkit page, select **Next** .

3. Read the license agreement. If you accept the agreement, select the
   **Iaccepttheagreement** option and select **Next** .

4. Browse to a directory where you want Migration Toolkit to be
   installed, or allow the installer to install Migration Toolkit in the
   default location. Select **Next** .

5. On the Ready to Install page, select **Next** .

An information box shows the installation progress of the selected
components. This may take a few minutes.

1. When the installation has completed, select **Finish** .

After installing Migration Toolkit, you must install the appropriate
JDBC drivers before performing a migration. See :ref:`Installing a JDBC driver <Installing a JDBC driver>`  for more
information.
