I would have suggested switching to a TCA, either amitriptyline, or imipramine, but is SSRIs are preferable than escitalopram is as likely to work as another SSRI. It and citalopram have good records for working when another SSRI has failed, though your previous use may reduce the chances a little.

If so, is it better to tapper of sertraline and start at the same time escitalopram (I'm at 100mg sertraline, so it would be 50mg sertraline and 5 mg escitalopram, then after 5 days no sertraline 10mg escitalopram and after 10 days 20mg escitalopram)? Or to tapper of sertraline for 5 days and then start escitalopram?
You're likely to do okay with the cross taper option, or you could do an overnight switch from 100mg sertraline to 10mg escitalopram increasing the dose to 20mg escitalopram after a week. There is no need to taper off one SSRI before starting another (or a TCA). This only delays the recovery for little if any gain, ime.
