Prerequisites

2.1 Prerequisites

You must perform the following tasks to set up the migration environment:

Verify if the mated site has the capacity to handle the traffic. For information, contact My Oracle Support.
Run the following command on the Host hardware to check the IP connectivity between BM and VM host hardware.
```
ping (baremetal DSR NOAM IP)
```
Divert all the traffic to the mated site.
Take a backup of all the servers from the DSR GUI as described in Full Backup of DB Run Environment at Each Server in DSR Cloud Software Upgrade Guide.
Export DSR 8.6.x configuration data from NOAM and SOAM as described in Exporting Configuration Data on DSR 8.6.X.
Run the following commands on Active and Standby NOAM and SOAM one after another:
```
iset -fvalue=1 IdbParamDef where "param='IdbDisableUpgBarrier'"
sudo init 6
```
Run the following commands on all C level servers one after another:
```
iset -fvalue=1 IdbParamDef where "param='IdbDisableUpgBarrier'"
sudo init 6
```

Note:

Store the backed up data on a remote server. This data is required while performing backout.

The following table provides the time requirement by each task while performing migration from BareMetal DSR 8.6.X to DSR 9.0.x VM.

Table 2-1 Time Required for DSR Migration

Procedure	Time Required in minutes
Step 1 - Preparing check list and verifying it	20
Step 2 - Prerequisite checking and procedures	140 Note: Provided assuming 2 DR NOAM, 2 NOAM, 2 SOAM
Step 3 - Standby DR NOAM Migration	86
Step 4 - Active DR NOAM Migration	80
Step 5 - Standby NOAM Migration	80
Active NOAM Migration	80
Standby SOAM Migration	80
Active SOAM Migration	80
Standby IPFE Migration	80
Active IPFE Migration	80
1 DAMP Migration	80 Note: DAMP time is based on the number of DAMPs and number of DAMPs in single cycle.
1 SBR Server Group Migration	240 Note: Data migration is not considered. Data migration time is based on the number of sessions and binding. The time mentioned here is for one SBR SG. Time is multiplied for number of SGs.
KVM/Openstack Installation	120 Note: Installation and configuration time may vary based on the customer topology size.
KVM/Openstack configuration	120
Total	1366
