Timelines for upgrade to AC 10.0

Dear Experts

We have Access control RAR 5.3 and SPM 5.3 in the landscape and want to up-grade to 10.0 upon release.

Please let us know the indicative timelines for up-grade to AC 10.0 from AC 5.3 (only RAR and SPM) inluding testing. We only have ECC 6.0 connected to these components and we are using SAP standard ruleset.

Regards
