WSO2有一些关于版本之间升级的很好的文档，但我们有版本4.5.3，如果我可以直接从4.5.3升级到5.1.0，我在文档中看不到？
他们的文档介于各级之间，例如4.5.3到4.6,4.6到5.0,5.0到5.1。
是否有直接从4.5.3过程到5.1的过程（无需进行临时级别）？

不，我们提供从当前版本迁移到下一版本的步骤。您必须逐步迁移。或者您可以组合这些步骤并进行迁移。
为两个不相关的版本提供迁移脚本是不可扩展的。想象我们必须维护多少个脚本组合。

You can't migrate directly from 4.5.3 to 5.1.0, you have to do incremental migration. Other than that recently we released the new G-Reg 5.2.0 which is a much more improved version of 5.1.0, therefore we prefer you to use the latest version possible.
We have tested these migrations scripts in our local environments and it won't take that much time to migrate. lets say you have 500 artifacts in G-Reg 4.5.3 and it will take less than 2 days to do the migrations till G-Reg 5.2.0. By looking at the benefits your getting after the migration I think the time/resource consumed will worth a lot.
Please find the official documentation for Upgrading from a Previous Release. Please download the all new G-Reg 5.2.0 from here.
