Guideline 1. Only the old TR and the new TR should carry out the transfer of SFT data. The new TR should not accept duplicate reports by TR participants relating to SFTs subject to transfer. The old TR should not accept reports with action types "ETRM" and "EROR" made by TR participants relating to SFTs subject to transfer.

Guideline 2. The transfer of data should be carried out by the TRs in accordance with a mutually agreed migration plan. The migration plan should contain the detailed planning (timeline) and a description of the required controls in place to ensure the timely, complete and accurate transfer of data.

 Guideline 3. All TRs should use a standardised migration plan template mutually agreed across all TRs and that is compliant with the content included in Guideline 4.

Guideline 4. The migration plan should contain the following information:

(i) the scope of the data transfer (e.g. the TR participant(s), SFTs involved, etc.);

(ii) detailed roles and responsibilities of the involved entities;

(iii) timeline and relevant milestones for the transfer;

(iv) the controls required to ensure the confidentiality of the transferred data (e.g. type of encryption used);

(v) the controls required to ensure the integrity and accuracy of the transferred data (e.g. cryptographic checksums and hashing algorithms);

(vi) the controls required to ensure continuity of operations and the inter-TR reconciliation status of the SFTs under transfer;
