The following steps should be performed before creating a web farm:
Normally, this means making sure that TCP port 445 is open between any of the MOVEit DMZ 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 Adminstrators group on the MOVEit DMZ server. For more information about configuring the NAS, see the Remote Filesystem doc page.
If the MOVEit DMZ 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. Please see our knowledge base article on converting MOVEit DMZ to SQL Server for more information.
