1. Use a VM for the nmis9 server: We would need to run additional steps to migrate the data. 
2. Install the apps one the data is migrated: The installers will upgrade the data to the new format. 

Upgrade process: Using nmis9 VM (NMIS9)

Prerequisites

• NMIS 9 and OMK apps are installed on the server. 

...

Here you can find further information.

Step 3. Copy RRDs

This can be done really easy with rsync:

rsync -r root@uburnto.opmantek.net:/usr/local/nmis8/database/nodes /usr/local/nmis9/database

Then fix permissions:

/usr/local/nmis9/bin/nmis-cli act=fixperms

Run script to adapt names

This script will adapt nmis8 rrd names to nmis9 (From nmis 9.2.1):

/usr/local/nmis9/admin/node_admin.pl act=move-nmis8-rrd-files {node=nodeX|ALL|uuid=nodeUUID} [remove_old=1] [force=1]

Step 4. Import Nodes

We have copied the nodes file from nmis8 using rsync. We would need to import the nodes now:

/usr/local/nmis9/admin/node_admin.pl act=import_bulk nodes=/usr/local/nmis9/conf/Nodes.nmis debug=true

Step 5. Verify

We can start nmis9d. Depending on the number of nodes, we should leave it running for more or less time. 

We can open nmis9 and you should see the nodes with the rrd information:

Upgrade process: Using nmis9 VM (OMK)

Prerequisites

• NMIS 9 and OMK apps are installed on the server. 
• All the services had been stoped 

Step 1. Move and adapt OMK files

Configuration Files

Copy

Copy the configuration directory from the source server.

...

ln -s ../nmis9/conf/users.dat conf/users.dat

Step

This can be done really easy with rsync:

rsync -r root@uburnto.opmantek.net:/usr/local/nmis8/database/nodes /usr/local/nmis9/database

Then fix permissions:

/usr/local/nmis9/bin/nmis-cli act=fixperms

Run script to adapt names

2.

...

/usr/local/nmis9/admin/node_admin.pl act=move-nmis8-rrd-files {node=nodeX|ALL|uuid=nodeUUID} [remove_old=1] [force=1]

Step 5. Import Nodes

We have copied the nodes file from nmis8 using rsync. We would need to import the nodes now:

/usr/local/nmis9/admin/node_admin.pl act=import_bulk nodes=/usr/local/nmis9/conf/Nodes.nmis debug=true

...

 Move OMK Database

• Stop services in origin server
• Generate mongodump:

...

mongorestore -u opUserRW -p op42flow42 mongodump/
