1，首先要准备原始邮箱，这个和提SR差不多。
P.S:如果没有原邮的，通过登录邮箱也是可以申请的
2，登录（没有就注册）https://store-oracle.custhelp.com/app/STORE_CP
这个服务网址还接受（升级成功后）扩区申请
按要求填写*的所有选项
A、主要是标题：Request support: Error upgrading paid account
B、然后就是内容：
Dear Oracle Support Team,My Oracle account is [*****].During the account upgrade process, I encountered the following error: [It was not possible to complete your upgrade. Common registration errors occur because of: (a) Use of prepaid cards. Oracle only accepts credit and debit cards (b) Intentional or unintentional masking of location or identity information (c) Incomplete or incorrect account data entry. Please try again if this applies to you. Otherwise, contact Oracle Customer Support.]. I have already attempted to resolve it by restarting my device, clearing browser cache, and even attempting the upgrade on different networks, but the issue persists. Given that this upgrade is directly related to my daily work and studies, I am in urgent need of your technical support to resolve this matter.
以上内容我是通过GPT生成的，已经提交过了一次了，请不要完全照搬。
提交后会有一个Incident: 2307**-000***的邮件反馈到你的邮箱，表示他们已经受理。
如果48小时还没收到回复（节假日除外），进入https://support.oracle.com，附上Incident: 2307**-000***提个非技术支持的SR，一般在24小时内会解决。
刚已经通过以上网址扩区成功了。祝大家升级/扩区成功！
再附一个升级团队官方的在线聊天网页：https://store-oracle.custhelp.com
扩区成功的答复：
