• Temporarily disable any antivirus software auto-scans on the destination virtual server host
to prevent interrupting the migration process. Re-enable the antivirus software after the
migration.
Preparing for a Linux server migration
The following sections list prerequisites for a Linux server migration.
• If you use a firewall, see “Disabling firewalls” (page 25).
• Verify compliance with all minimum prerequisites. See “Minimum source server prerequisites
for all migrations” (page 43).
Source physical server prerequisites
If migrating from a source physical server, verify that the following prerequisites are complete:
• Comply with all minimum prerequisites as listed in “Minimum source server prerequisites
for all migrations” (page 43).
• PermitRootLogin and PasswordAuthentication are set to Yes in the /etc/sshd/sshd_config
file and the sshd service is running.
• The GRUB Boot Loader is required as the primary boot loader on the source server.
Source virtual server prerequisites
If migrating from a source virtual server, verify that the following prerequisites are complete:
• Comply with all minimum prerequisites as listed in “Minimum source server prerequisites
for all migrations” (page 43).
• PermitRootLogin and PasswordAuthentication are set to Yes in the /etc/sshd/sshd_config
file and the sshd service is running.
• The GRUB Boot Loader is the primary boot loader on the source server.
• Firewall is disabled.
• Guest tools are uninstalled.
Destination physical server prerequisites
If migrating to a destination physical server, verify that the following prerequisites are complete:
• The primary storage controller must be configured with drives attached.
• The destination server must be booted to Insight Control server migration Boot CD ISO and
running migration agent.
Destination virtual server host or virtual server prerequisites
If migrating to a destination virtual server, verify that the following prerequisites are complete:
• Select one of the following:
— Let Insight Control create the virtual server automatically, and then boot it using the
Insight Control server migration Virtual Machine Boot CD ISO for virtual servers.
— Create the virtual server manually, and then boot the virtual server manually using the
Insight Control server migration Virtual Machine Boot CD ISO.
• Verify that the destination virtual server host has sufficient system resources, including
processor, memory, and disk space to host the migrated virtual server guest.
• Temporarily disable any antivirus software auto-scans on the destination virtual server host
to prevent interrupting the migration process. Re-enable the antivirus software after the
migration.
