Older Microarray probes not matching Ensembl genes

Question

[Krish Srinivasan]

Hello,

I have some old microarray data from a zebrafish experiment done years ago. The probes are Agilent G2519f. When i input a small subset of probes into Biomart on ensembl to get genes, over half of these probes do not seem to be representing a gene. Is there some way to update the probes to the current ensembl annotation (87).

Thanks
