So why are you asking for the replacement in Hibernate 6 then? You should update to 5.6.6.Final which will un-deprecate the @Type annotation. In 6.0 the annotation was changed to only accept UserType class literals.
Not sure what this question has to do with Hibernate Search 6 since this is an annotation from Hibernate ORM, but like I wrote, the deprecation was removed in newer versions of Hibernate ORM 5.6
Sorry It was my confusion . Initially I though this annotation is from Hibernate Search 6.
After upgrading to 5.6.6 type annotation got un-deprecated. I hope with 5.6.6 there should not be any impact on hibernate search 6.0
