Do the following before you create a web farm:
Normally, this means making sure that TCP port 445 is open between any of the MOVEit Transfer nodes and the NAS.
This NAS account must be granted FULL access to the shared folder. The NAS account you create or select MUST be a member of the Local Administrators group on the MOVEit Transfer server. For more information about configuring the NAS, see the Remote Filesystem doc page.
If the MOVEit Transfer database is not already present on the web farm database server, it must be copied there before creating a web farm. If you are electing to migrate to a remote SQL Server database from a local MySQL database in addition to creating a web farm, perform that migration at this time. For more information, see How do I convert the MOVEit DMZ database from MySQL to Microsoft SQL Server.
Note: When you upgrade a MOVEit Transfer Server node, ensure that the local logs directory defined in the Web Farm install configuration for all nodes already exists and uses the same path for all nodes (or else create one on each node). If the installer does not find this local logs directory, it will return a failure message and halt during the Web Farm scale-out process.
