Creating replica of a cube with same members with unique description and aliases.

Summary: There is a client requirement in which as per regulatory existing cube needs to be restructured as new compliance in which the metadata members structure should be same but the alias and description should be different and they want both new and old aliases as description to be in the system.

For ex- For FY26, an account with name EXB10001 - Description - Accounting Policies- ICDS I,

For FY27 same account but different description and alias.

Can anyone please suggest if there is any technique/feature to implement this?
