My general protocol for upgrades that makes me pretty successful:

1. Make sure you have enough free space:
2. Make sure your configs verify (no errors is what we want, don't care about warnings)
3. Make sure you don't have any crashed tables:

First, run it to see the sizes (to make sure it outputs valid data):
- NOTE: You may need to adjust the -h 127.0.0.1, the -uroot, and -pnagiosxi in the first command if your DB is offloaded to another server and/or you've changed the root mysql password
Then you can run it like this to check for crashed tables:
- NOTE: You may need to adjust the -h 127.0.0.1, the -uroot, and -pnagiosxi in the first command if your DB is offloaded to another server and/or you've changed the root mysql password
If no NULL are found, no crashed tables. (NULL means it was unable to calculate that tables size so it means the table is crashed)

4. Backup XI/VM Snap (just in case):

5. Reboot server, wait 15 minutes, this will ensure everything is fresh and up and running.

6. Follow the manual upgrade process from the CLI, if it fails, send us the upgrade.log file from the installation directory (generally /tmp/nagiosxi/upgrade.log) so that we can help you work through any issues.

Since you're running XI 2014R2.7 I would go straight to XI 5.6.5 (latest).

Let us know if you have any questions or if we can clarify anything.

Hello SSAX,

1- Is Nagios XI 5.6.5 (latest) Supports mod_gearman as we have config the mod ?

2- Regarding the Upgrade we have already opened the Ticket - 509439 earlier and support team taken multiple remote sessions but due to different RHEL version 6/7 they advised to each library import/export manually.

As per our our recommendation we are thinking to follow the below steps provide your inputs if we are following the correct procedure -

Step 1- Take backup/clone from current NAGIOS XI.
Step 2- Install Latest RHEL 7 on New server.
Step 3- Import Nagios XI clone/Backup on New server.
Step 4- check the functionality all working same as Nagios XI version: 5.5.5

1- Is Nagios XI 5.6.5 (latest) Supports mod_gearman as we have config the mod ?

Yes, Nagios XI 5.6.5 will work with Mod Gearman, but you will have to update it to version 3. See our official documentation on integrating Mod Gearman with Nagios XI here:
