Linux server migration can fail with the following error if the destination size chosen when you specify destination disks in the migration wizard, does not have enough space to create the <initrd
Server migration could not modify initrd on the destination server. This could happen when there is not enough free space available on boot partition. Increase free space on boot partition by deleting unused files or make sure that boot partition has 10MB or more of free space and retry migration process.
To resolve this issue, when you specify destination disks in the migration wizard, choose a destination size that is large enough to create the /boot/<initrd
Booting the destination server
Boot the destination server by using the applicable Insight Control server migration Boot CD ISO. To boot a destination physical server, you must be able to reboot the server and load through iLO. For virtual machines, you must have access to the management console for the virtual machine host. For information on choosing server migration agents, see “Choosing server migration Agents” (page 25).
There are Boot CD ISO files available to boot destination servers manually. However, HP recommends that you allow the server migration wizard to boot the destination server. You can do this by selecting the Auto Boot - Let server migration Boot the destination server option in Step 3 of the wizard. For more information, see “Booting a physical destination server automatically by using the migration wizard” (page 32) or check the Insight Control server migration online help.
•Insight Control server migration ProLiant Boot CD ISO file
You can use this ISO to manually boot a physical destination server for X2P migrations. This ISO is available after you install Insight Control server migration. To access the ISO, see the directory <Insight Control server migration Installation
•Insight Control server migration Virtual Machine Boot CD ISO file
You can use this ISO to manually boot the destination virtual machine guest for X2V migrations. This ISO is available after you install Insight Control server migration. To access the ISO, see the directory <Insight Control server migration Installation
The Insight Control server migration ProLiant or Virtual Machine Boot CD ISO can boot only supported destination servers. For a list of supported servers, see HP Insight Management Support Matrix at the following website:
http://www.hp.com/go/insightmanagement/docs
To manually or automatically boot the destination server or virtual machine to the proper Insight Control server migration Boot CD ISO, see the following procedures. After the destination system is booted, you must configure it to launch the destination agent.

NOTE: For Gen8 servers, the manual boot option is not supported.
1.Boot the server remotely by using the iLO virtual media feature.
2.After the destination server or virtual machine is booted to the proper Boot CD ISO file, use the Boot CD ISO application to configure the destination server and launch the destination Agent. From the Boot CD ISO application, click Help for instructions.
