Understanding Society User Support

I have a few questions related to the occupational coding. I want to study social mobility for which I need parents and respondent's occupations. I want to translate everything into either ISCO-88 or ISCO-08 codes. In the "www.ons.gov.uk" web page, only the conversion into ISCO-08 (from SOC 2010) is available... My questions are:

- I participated in the UKHLS train and there I got a database in which the ISCO-88 is coded for respondents. Is this based on the SOC 2000? Could I get the translation/syntax you have used for this? This way I could do the same for the parents.
- SOC 2010 is available for parents but not for respondents, why is this the case? Will SOC 2010 be available for respondents?

Thank you!
