Migration procedures 

HVM Navigator User's Guide - Migration 

Return migration 

Primary usages of Migration functions of HVM Navigator comprise forward and 

backward migrations between specific HVMs, thereby achieving such 
advantages as minimum server downtime at scheduled maintenance and 

optimum power saving through scheduled server consolidation during off-peak. 

In this manual, the backward migration from the destination to the source is 
called “return migration.” 

Return migration is executed with the source and the destination mutually 

swapped. Other operating steps are the same as those in the normal migration 
process. 

Exchanging or updating hardware or software 

By executing Concurrent Maintenance mode, you can exchange or update 

some kinds of hardware and software without suspending services provided by 

the LPAR. For the kinds of hardware and software, see Table 1-1. When you 
exchange or update any of the kinds of hardware and software, follow the 

procedure shown in Table 3-1. (As an example, the procedure to update HVM 

firmware is shown in Table 3-1.) 

Table 3-1 Procedure to update HVM firmware with Concurrent 

Maintenance mode 

Process 

No. 

Process

1

Return all LPARs to HVM 1. 

Return Migration in Migration procedures 

 

 

 

 

Where a periodic or scheduled server migration is to be deployed, it is 

recommended to execute a trial migration using Migration functions of HVM 

Navigator on the actual target servers and ensure normal operation of the 
migration destination in advance. Thereafter, you can restore these servers 

using return migration, and start production run. It is also recommended that 

you register a successful migration instance to a migration policy and execute 
policy migration, thus facilitating subsequent migration operation of the same 

nature.
