Im considering switching from Terraform to Pulumi for our infrastructure, but I would like to hear from people who already use it for some time what you found are the pros and cons in comparison to simply using Terraform.

Im planning to move a pretty big Infrastructure that consists of alot of services from AWS. Ps. It is not a serverless infrastructure tho it uses lambdas for some things. Around few thousends instances deployed in asgs + monitoring and some extras.

Does anyone has an expirience with similar migration to pulumi and what were the possible issues ? I would like to hear your opinion.
