No
FormerlySerializedAs Attribute doesn't save the serialized value when properties are used
How to reproduce:
1. Open the attached "case_1378365" project
2. Open the "Test" Scene
3. Select the "TestObj" GameObject in the Hierarchy
4. Set the "MyStringProperty" to any value that's in the "Serialized Property Example" Component in the Inspector
5. Rename the "MyStringProperty" variable to any name
6. Observe the renamed "MyStringProperty" value in the Inspector
Expected result: The "MyStringProperty" value is serialized and the renamed variable value is the same as what was set at the 4th step
Actual result: The renamed "MyStringProperty" value is an empty string
Reproducible with: 2019.4.35f1, 2020.3.27f1, 2021.2.9f1, 2022.1.0b4, 2022.2.0a2

Resolution Note:
Currently we do not support officially properties serialization. If you want FormerlySerializedAs to work on a backing field of a property you need to put in the name of the backing field: [field: SerializeField, FormerlySerializedAs("<MyStringProperty>k__BackingField")] , you can observe those names in the yaml file when saving your content in Unity Editor. Hope this helps.
