HI, We are running 3.9.1 via an AWS Cloudformation and would like to upgrade to the latest version which i believe is 3.15.3 in Cloudformation.
When i run the upgrade option and use the following url - https://thethingsindustries.s3.amazonaws.com/public/payg-ami-cloudformation-3.15.3.template
Part of the upgrade means i have to choose the Amazon RDS Postgres Version, according to my parameters i am currently on 11.4. The option tell me I have to stay within the current main version so my only option is 11.9.
However when i run the update i get an immediate failure to say
Cannot upgrade postgres from 11.12 to 11.9 (Service: AmazonRDS; Status Code: 400; Error Code: InvalidParameterCombination; Request ID: 767a95b3-b32a-44a3-9330-5faf8db304b2; Proxy: null)
Any pointers… I was thinking of binning the install and moving to the AWS SAAS managed version but i have several gateways and devices that i need to retain and can’t find anyway of backing up the system
