• 4 processors are required as a minimum. Using 8 or 16 processors is strongly recommended for faster processing. 
  • 16 gigabytes of RAM are required as a minimum. Using 32 or 64 gigabytes of RAM is recommended for the best performance.
  • Guideline: (4 CPUs requires 16 GB RAM, 8 CPUs requires 32 GB RAM, and 16 CPUs requires 64 GB RAM). Note: You must install CPUs and RAM in a 1 to 4 ratio. 
  • Recommended: 200 gigabytes of available hard disk space. System free space must be at least 150 GB after install of LinkFixer Advanced. 
  • Multiple computers to share the processing load are also recommended in production. LinkFixer Advanced can share its workload across multiple computers. In most cases, this can dramatically increase your processing speed and thus shorten your migration jobs. 



  • Windows 7 or newer operating system, or Windows Server 2008 R2 or newer.
  • Microsoft SQL Server 2012 SP4 or higher is required for optimal performance.
  • .NET 4.6.1 framework is required. This will be installed along with LinkFixer Advanced if not already present.
  • Ports that must remain open are: (80 (HTTP),443 (TCP HTTPS, Amazon S3), 53 (DNS), 8080 (HTTP), 22 (Support channel), 123 (NTP),111 (Amazon Data), 2049 (NFS), 20048 (NFS v3), 139(SMB v2), 445 (SMB v3) Port Requirements
