From AWS to GCP - Is downtime unavoidable during migration?

I'm trying to migrate a bitnami wordpress from AWS to GCP. I would like to avoid downtime during the migration. As a new learner, I am not sure how to best handle this.

I have encountered some roadblocks. Typically on Load Balancer and SSL

I would like to use a load balancer on GCP. I prefer Google's managed certificate but the domain's IP is tied to AWS's server. I have to release them from AWS first and that will be quite a bit of downtime waiting for GCP to validate and provision.
If I were to use own certificate on GCP's load balancer just for the migration purpose to avoid downtime, will there be downtime if I switch back to Google's managed SSL?
The bitnami wordpress VM's on GCP has a dummy self-signed root certificate pointing to example.com CN=example.com that I can't remove, more likely I don't know how to. How can I remove or replace that with actual domain name?
I am unable to generate a letsencrypt on GCP's server because the domain is still tied to AWS's server. Again, I have to release them first before I can use it on GCP and that will result in downtime.
If I use SSL on loadbalancer, do I still need to install SSL on server? Will the virtual host 443 work without SSL installed on the server?
Is it possible to create the loadbalancer without providing a SSL for frontend? I don't see an option to do so on GCP's console.

I understand my questions are probably very elementary. I really appreciate any directions at this point.

Thanks

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
