mdx points expire either 6 months from the date of issuance or at the end of the fiscal year, whichever comes first.
There are no refunds or reimbursements for points that expire unused.
Points can be purchased in units of 5,000 points (1 point = 1 yen), so please plan accordingly.

Trial projects cannot be converted to normal projects. If you wish to migrate the environment created in the trial project to a normal one, please create a new normal project and then clone the virtual machine using the OVF image before the trial project expires.

Cloning Procedures

Please refer to “10.4.4.1. Creating a virtual machine using OVF image“(Only available in Japanese).

Before proceeding, ensure that the status of the virtual machine is “Deallocated.”
To change the status to “Deallocated,” shut down the virtual machine, then navigate to ACTION > Maintenance > Deallocate.

During OVF export, data stored on virtual disks will be exported as disk images, but data stored on High Speed/Large Capacity storage will not be exported. After completing the OVF import, power on the virtual machine, and transfer any necessary data from High Speed/Large Capacity storage.

Transfer Procedures for Data Stored on Storage (Example)

  1. ACL and DNAT Settings

Configure to allow the global IP assigned to the source project to be permitted in the destination project.

[Source Project]

Example DNAT settings:

  • Source global IPv4 address: Global IPv4 address assigned to the source project (Virtual Machine A).
  • Segment: Segment used in the source project (Virtual Machine A).
  • Destination private IP address: Private IPv4 address used in the source project (Virtual Machine A)

[Destination Project]

Example ACL settings:

  • Src address: Global IPv4 address of the source project (Virtual Machine A).
  • SrcPrefix length: 32.
  • SrcPort: Any.
  • Dst address: Destination private IP address of the destination project (Virtual Machine B).
  • DstPrefix length: 32.
  • Dst port: 22.
  • Protocol: TCP.

Example DNAT Configuration:

  • Source global IPv4 address: Global IPv4 address assigned to the destination project (Virtual Machine B).
  • Segment: Segment used in the destination project (Virtual Machine B).
  • Destination private IP address: Private IPv4 address used in the destination project (Virtual Machine B).

  1. Data Transfer

To transfer data from the source project (Virtual Machine A) to the destination project (Virtual Machine B) using rsync.

Example:

If the source area is a large capacity storage (/large) and the destination area is also a large capacity storage (/large):

$ rsync -av /large/[source directory name] [destination global IPv4 address]:/large/[destination directory name]”
