Requirements:

A valid Veeam10 license in the Abiquo UI
Access to port 9398 (HTTPS) of the Veeam EM server (because 9399 HTTP has been deprecated)
- See https://helpcenter.veeam.com/docs/backup/em_rest/ssl_encryption.html?ver=110
You must upgrade Veeam Enterprise Manager and Veeam Backup and Replication

Steps:

On all Remote Services servers

Edit abiquo.properties file, and add these properties

abiquo.virtualfactory.veeam10.backup.openSession=1
abiquo.virtualfactory.veeam10.backup.openSession.byvdc=false
abiquo.nars.async.pool.veeam10.max=1
abiquo.nars.async.pool.veeam10.byvdc=false

And remove these deprecated properties

abiquo.virtualfactory.veeam95.backup.openSession
abiquo.virtualfactory.veeam95.backup.openSession.byvdc
abiquo.nars.async.pool.veeam95.max
abiquo.nars.async.pool.veeam95.byvdc

Edit veeam.properties file, and modify the API version
```
avbc.veeam.restapi.version=v1_5
```

On the API server, edit Abiquo properties, and modify "veeam95u4" to "veeam10"

abiquo.plugin-client.timeout.veeam10.getexpiredresults=3600000
abiquo.plugin-client.timeout.veeam10.listresults=3600000

On ALL servers, restart the abiquo-tomcat service
Log in to Abiquo as an administrator
1. Delete the current backup manager of type "Veeam backup plugin 9.5 update 4"
2. Add a new one of type "Veeam backup plugin 10" with the correct endpoint protocol, for example: "https://veeam.example.com:9398/api/"
Check all the requirements of your environment, such as:
1. Veeam dummy jobs
2. Backup policies with code to match the name of the backup policy in Veeam
3. Network connectivity
