For increise SLA I need to change Azure LoadBalancer SKU,
Azure LB Basic don’t have SLA, different is for Standard SKU.
Don’t is possibile to change the sku with a upgrade, the only solution is create a new LoadBalancer (Standard) e configure it with the configuration of old LoadBalancer (Basic).
Luckily Microsoft have release a procedure for made it.
We need check if our LoadBalancer is Public or Internal (No Outbound or With Outbound)
For any choose we have a script to use. Very easy.
What are the steps of the script?
1- Save and change (with new free IPs) the frontend IPs of Basic LoadBalancer (the script support only 5 Frontend IPs, for more IPs you manually pass the IPs)
2- Create a new Standard LoadBalancer with the configuration of basic loadbalancer (Frontend IP, Probe ecc..)
3- Migrate the backend pool
In my upgrade we have been a ten minutes of downtime.
