I need an existing website rebuilt.
Who can do this? (At a moderate amount.)
Required task is therefore a „logical“ downgrade from MySQL 5.6 two 5.5. Please refer to: https://dev.mysql.com/doc/refman/5.6/en/downgrading.html#downgrade-procedure-logical . As far as I understand, the existing databases have to be exported from 5.6 and then imported into 5.5. Previous condition therefor is obviously a running 5.6 instance, before the export can be made.
The new provider in Germany, 1&1, uses MySQL 5.5.
Until recently, the homepage was running at a provider in USA under MySQL 5.6.32. WordPress Backup is available (complete, with files, as well as only with data bases).
