I am currently using ElasticSearch 2.3.x and NEST client v2.5.2.
I want to upgrade to ElasticSearch 7.x and therefore upgrade NEST.
Unfortunately, my projects are currently targeting the .NET Framework 4.5.2 (and I can not upgrade for an upper version for the moment) and the most updated versions of NEST (v6.3 to v6.8) are targeting .NET Framework 4.6.
I am thinking about using NEST v6.2 until I can upgrade the .NET Framework, will it be fully compatible with ElasticSearch v7.x ?
I would strongly recommend upgrading from .NET 4.5.2 as soon as you can, if you can. Whilst technically still supported by Microsoft at this time, it's now over 5 years old and superseded by several minor and patch versions.
