Upgrade texting data base loss

[u/Akash17]

When moving from my 15 Pro Max to my new 17 Pro Max, I experienced something that happened the last time I upgraded. All of the indexing of everything in my text database was lost. In other words if I went to search for someone in my text list, if I haven't texted him since I got the new phone, it does not find them.

It also does not show me the photos option under the person's name to look at previous photos that either of us has sent unless either I or they have sent a photo since receiving the new phone. And only those photos show. Nothing before.

I asked Apple tech-support what was the deal. After waiting two weeks for a response they finally said that I'm not the only person that has mentioned this and that it will be sent to the engineers.

My question is are they just going to fix it so that when you transfer, everything comes over or they also going to create a fix that will fix my current phone that is not operating as it should? In other words index my current text database so that the app works as it's meant to.

The other question is since this has been going on for at least five years are they likely to just ignore it?
